Another Time, Another Place (#6)

Another Time, Another Place Screenplay by Johnny Byrne
Directed by David Tomblin
Edited by Derek Hyde Chambers

"I knew you didn't die. I knew."

The Moon passes through a rift in space and Regina Kesslann is badly effected by the experience. She develops the symptoms of sunburn and suffers an emotional breakdown when she discovers that John Koenig and Alan Carter are still alive - particularly Carter, to whom she believes she is married. Incredibly, the Moon returns to Earth, but an identical Moon is already in the planet's orbit. Regina dies suddenly and an autopsy reveals that she has two brains! Koenig and Carter visit the doppelgänger Moon where they find an abandoned Moonbase Alpha and a crashed Eagle with their own bodies at the controls. Realising that they have travelled through time and caught up with their future selves, Koenig leads a team to Earth to discover the final fate of the Alphan survivors...

Filming Schedule:

This episode marks the series debut of director David Tomblin who was brought in to the series to replace outgoing director Lee H. Katzin. One of the film industry's most sought-after assistant directors, Tomblin's previous work included such films as Taste Of Fear (1961), The Haunting (1963), Murder Ahoy (1964) and Shaft In Africa (1973), although he had also directed series television including episodes of The Prisoner (on which he also served as producer), and both UFO and The Protectors for Gerry Anderson. As first assistant director and second unit director, Tomblin has subsequently worked on Barry Lyndon (1975), The Omen (1976), A Bridge Too Far (1977), Superman (1978), The Empire Strikes Back (1980), Raiders Of The Lost Ark (1981), Return Of The Jedi (1983), Never Say Never Again (1983), Indiana Jones And The Temple Of Doom (1984), Out Of Africa (1985), Indiana Jones And The Last Crusade (1989), Braveheart (1995) and The Man In The Iron Mask (1998).

The episode also features the first complete original screenplay by Johnny Byrne who replaced Edward di Lorenzo as the series' script editor.

For split-screen scenes on the future Earth, Zienia Merton played the duplicate Dr. Russell opposite Barbara Bain on the studio floor - her side of the screen was masked off and double-exposed when the two actresses swapped position to create the effect of two Helenas talking to each other.

Nick Tate has often cited this as his favourite episode of the series.

Guest Artists:

Judy Geeson made her film debut in Wings Of Mystery (1963), but first found acclaim for her role as Pamela Dare in To Sir With Love (1967), a role that she recently reprised in the TV movie To Sir With Love 2 (1996).

Missing Link (#7)

Missing Link Screenplay by Edward di Lorenzo
Directed by Ray Austin
Edited by Mike Campbell

"It is not a dream, but all very real I assure you."

Koenig is critically injured when his Eagle crashes on the lunar surface. Apparently in a coma and relying on life-support to sustain him, Koenig awakes to find himself transported to a city of light on the planet Zenno where Raan, an alien scientist, believes him to be the missing link of the loveless Zennite people. Initially reticent to comply with Raan's experiments, Koenig is seduced by the scientist's beautiful daughter Vana, and begins to have second thoughts of returning to Alpha, opting for a peaceful, immortal existence on Zenno, free at last of the constant fight for survival. Back on Alpha, however, Koenig's body is dying and the command structure is breaking down - without Koenig to lead the Alphans, the base is falling apart!

Original UK Airdate: Thursday, January 22nd, 1976 (ATV Midlands)


Some of the incidental music in this episode was composed and recorded in 1963 for the Stingray episode Ghost Of The Sea. The track of electronic organ music used for "Vana's Theme" was originally composed by Barry Gray & Alan Willis for Breakaway as a theme for establishing shots of Moonbase Alpha - unused in the completed episode, it makes its sole appearance in the series here. In some shots of the medical monitors, Koenig's name is incorrectly spelled "KEONIG".

Guest Artists:

Peter Cushing is internationally reknowned for his many appearances in the Hammer horror films and as Sherlock Holmes in the 16-part 1969 BBC series. He made his film debut in The Man In The Iron Mask (1939) and followed this with a small role in the Laurel & Hardy feature A Chump At Oxford (1939). Over his fifty-year career he appeared in some 90 feature films including The Curse Of Frankenstein (1958), The Abominable Snowman (1957), Dracula (1958), The Hound Of The Baskervilles (1959), The Mummy (1959), The Hellfire Club (1960), Dr. Terror's House Of Horrors (1964), She (1965), Dr. Who And The Daleks (1965), Daleks' Invasion Earth 2150 AD (1966), Night Of The Big Heat (1967), The House That Dripped Blood (1970), Twins Of Evil (1971), Tales From The Crypt (1971), Asylum (1972), At The Earth's Core (1976), Star Wars (1977), Arabian Adventure (1978) and Top Secret!

Guardian of Piri (#8)

Guardian of Piri Screenplay by Christopher Penfold*
Story by David Weir*
Directed by Charles Crichton
Edited by Derek Hyde Chambers

"Leave me with my pain. It reminds me I'm human."

The Alpha Main Computer falls under the control of the Guardian of Piri and reports that Piri is the perfect world that the Alphans have been looking for. When an Eagle crew go missing on the planet, Koenig leads a search party and discovers that Piri is completely lifeless. Locating the missing men, he finds them unwilling to leave, and back on Alpha he is betrayed by his colleagues who have succumbed to the Guardian's influence and set about the complete evacuation of the base. Taunted by the Guardian's beautiful servant, Koenig returns to the planet, determined to reveal the truth to his people about life on Piri...

Filming Schedule:
Friday, May 10th - Tuesday, May 28th, 1974

Original UK Airdate: Thursday, November 13th, 1975 (ATV Midlands)
Original Title: "Nobody's Perfect"


The episode features the first complete original screenplay by Christopher Penfold, who is credited as 'story consultant' on the in-show titles but, oddly, not as the scriptwriter. Keith Wilson's remarkable designs for the planet Piri resulted from discussions with Penfold about a play called "Spawn" that he had written for LWT, in which one of the main characters was a sculptor who filled the front garden of a country house with a sculpture that looked like pieces of frogspawn.

Catherine Schell makes her Space:1999 debut in this episode, albeit in a different role from that in which she was to appear as a regular in Year Two.

The New Avengers star Gareth Hunt is seen briefly (and uncredited) as an Eagle pilot in scenes at the end of the episode as the Alphans flee Piri. His role was originally intended to be much larger, but he had a disagreement with director Charles Crichton and left the production before the episode was completed.

Kano is revealed to have a complex of fibre sensors implanted in the cortex of his brain so that he can be linked to Main Computer.

The incidental 'theme' for Piri is "Undersea" composed by Chuck Cassey, a track from the Chappell Recorded Music Library.

Guest Artists:

Catherine Schell (real name Catherina Schell von Bauschlott) came to prominence in the James Bond film On Her Majesty's Secret Service (1969) but her film career includes appearances in Moon Zero Two (1969), Callan (1972), The Black Windmill (1974), The Return Of The Pink Panther (1974) and The Prisoner Of Zenda (1979). On television, she has been seen in The Persuaders!, Arthur Of The Britons, Supernatural, The Adventurer, The Sweeney, Return Of The Saint, Bergerac and Doctor Who, but apart from her role as Maya in the second series of Space:1999, she is best-known for her regular role as Virginia in the third series of Wish Me Luck.

Michael Culver is a familiar face on British television and best-known for his roles as Squire Armstrong in The Adventures Of Black Beauty, Major Fairjean in The Duchess Of Duke Street, Major Brandt in Secret Army, Dicky Cruyer in Game, Set And Match, Ralph Saroyan in The House Of Elliott and, more recently, Prior Robert in Cadfael. He has also made numerous guest appearances in series such as Doomwatch, The Persuaders!, The Sweeney, The New Avengers, Hammer House Of Horror, Breakaway, Shoestring, The Professionals, Miss Marple, Lovejoy, Boon, The Bounder and NeverWhere. His feature film appearances include Crossplot (1969), Goodbye, Mr. Chips (1969), The Empire Strikes Back (1980) and A Passage To India (1984).

Force of Life (#9)

Force of Life Screenplay by Johnny Byrne
Directed by David Tomblin
Edited by Alan Killick

"You could accept a freak electrical discharge from space once - but not twice!"

A ball of blue light approaches Alpha and while the personnel are suspended in time, the light invades the body of technician Anton Zoref. Everything apparently returns to normal but massive energy losses are recorded and Koenig begins to suspect that Zoref may be the cause. Possessed with a consuming need for heat, Zoref draws it from any source, human or otherwise, as he rampages through the base leaving a trail of dead bodies and useless equipment in his wake. Koenig orders power supplies to be cut in an attempt to deprive Zoref of light and warmth, but Zoref heads for the nuclear generating area...

Monday, July 1st - Friday, July 5th, 1974

Original UK Airdate: Thursday, September 11th, 1975 (ATV Midlands)
Original Title: "Force Of Evil"


This episode relies heavily on three pieces of electronic music from the Chappell Recorded Music Library: "Cosmic Sounds No. 1", "Cosmic Sounds No. 3" and "Videotronics No. 3" all composed by Roger Roger (aka Cecil Leuter) & Georges Teperino (aka Nino Nardini). The piped music heard in the Alpha solarium is "The Latest Fashion" by Giampiero Boneschi, also from Chappell's.

Guest Artists:

Alpha Child (#10)

Alpha Child Screenplay by Christopher Penfold, Edward di Lorenzo*
Directed by Ray Austin
Edited by Derek Hyde Chambers
*Christopher Penfold receives sole writing credit

"I saw him smile. It sent a shiver up my spine. So knowing - almost as if he were mocking his mother's death."

The first child born on the Moon inexplicably grows to the size of a five year old within a matter of hours and Koenig believes that the child's unnatural development is linked to the death of his father, a technician in the nuclear generating plant. Then four spaceships appear over Alpha, menacing the base and resisting all attempts to repel them. Jackie suddenly grows into a mature adult, revealing himself to be Jarak, one of 120 alien travellers who seek physical forms in which to conceal their identities and escape the rigorously imposed genetic conformity of their home planet. He and his companions intend to inhabit the Alphans' bodies, which they can only do at the moments of birth and death...

Filming Schedule:
Monday, July 8th - Monday, July 22nd, 1974

Original UK Airdate: Thursday, October 16th, 1975 (ATV Midlands)


The original script of this episode was written by Edward di Lorenzo but re-written by Christopher Penfold who receives sole credit.

Some of the incidental music in this episode was originally composed and recorded in 1969 for the The Secret Service episode Last Train To Bufflers Halt.

Prentis Hancock has a nasty bruise under the nail of his forefinger which is still visible in The Last Sunset.

Barry Morse took some time off during filming of this episode and appears in only a couple of short scenes.

Guest Artists:

Julian Glover is primarily known for his many villainous roles, perhaps the best-known of which are his portrayals of Colonel Breen in Quatermass And The Pit (1967), General Veers in The Empire Strikes Back (1980), Aris Kristatos in For Your Eyes Only (1981) and Walter Donovan in Indiana Jones And The Last Crusade (1989). He made his feature film debut in Tom Jones (1963) and went on to appear in Theatre Of Death (1967), The Magus (1968), Alfred The Great (1969), Wuthering Heights (1970), Nicholas And Alexandra (1971), Juggernaut (1974), The Internecine Project (1974), Heat And Dust (1982), Cry Freedom (1987), The Fourth Protocol (1987) and King Ralph (1991). In the 1960s and 70s, Glover carved a niche for himself in television with numerous guest roles in series such as The Avengers (four times), Doctor Who (twice), The Saint, The Champions, Callan, Jason King, The Sweeney and Blakes 7. He has also guested in Magnum p.i., Remington Steele, Bergerac and Midsomer Murders, while his regular television roles have included Colonel James Cadogan in Wish Me Luck, Lord Revelstroke in Nancy Astor, Andrew Blake in The Chief, Dr. Stefan Kilkiss in the short-lived Q.E.D. and the starring role as Sir Martin Lacey in By The Sword Divided. He is married to actress Isla Blair, seen in War Games and Journey To Where.

Cyd Hayman is best-known for her leading role as Nina in the 1970 LWT wartime drama Manhunt. She later made a guest appearance in the Anyone Can Play episode of ITC's The Persuaders! before starring as Adele Torbayan in Clochemerle, and making regular appearances on The Two Ronnies. Her feature films include Percy (1971), The Human Factor (1980), The Godsend (1980) and Mask Of Murder (1985). She appeared in the A Man With A Fortune episode of Tales Of The Unexpected and as the glamourous neighbour Mrs. Kelly in the BBC2 comedy Lame Ducks.
