Murder in Space was a whodunnit murder mystery suspense film that featured on ITV screens in the UK on the 13th August 1985. The film was in fact a first so far as I know, as it was the UK's first nationwide whodunnit competition involving a film. Run in conjunction with the TV Times magazine, entrants had to name the characters responsible for the various murders in the film. As well as being able to watch the film, people who were keen to enter could also ring a telephone service and listen to recordings of interviews with the characters before they began the mission aboard the Conestoga. I remember as I did enter the competition but was only 13 at the time and was smitten with Michael Ironside ( still am lol). The second part which was the ending divulged the identity of the killers. It formed part of a TV show hosted by -the then popular- Anneka Rice and was screened in the autumn (Sept or Oct?) Several contestants were on the show who had correctly identified the killers, but only one guessed all of them and won the prize.
