Barbara Mason, John Nolan as Geoff Hardcastle, John Bown as Commander Neil Stafford, Jean Trend as Dr. Fay Chantry, Elizabeth Weaver as Dr Anne Tarrant, and Moultrie Kelsall as Drummond. Throughout its run, Doomwatch was produced by Terence Dudley, who also contributed several scripts himself. Dudley went on to produce another well-remembered BBC science-fiction drama, Survivors, and in the early 1980s wrote and directed episodes of Doctor Who. Aside from Davis, Pedler and Dudley, several other writers wrote episodes for the programme, including well-known veterans of several other British television science-fiction productions such as Robert Holmes, Dennis Spooner and Louis Marks. Spin-off film The Doomwatch feature film was produced by Tigon British Film Productions Ltd under licence from the BBC, and released in 1972. The script was based on a screenplay by Clive Exton from a story by Davis and Pedler. The television series' main characters appeared, played by their original actors, but main billing was given Ian Bannen and Judy Geeson as new characters. The film also featured George Sanders. Revival In 1999, Channel 5 bought the rights to revive Doomwatch from the BBC, and on 7 December that year screened a 100-minute TV movie produced by the independent production company Working Title Television. Subtitled Winter Angel, the television movie was a continuation of the story rather than a remake. Written by John Howlett and Ian McDonald, only one of the original characters from the series appears, an aged Dr Spencer Quist—now played by actor Philip Stone, as John Paul had died in 1995. Quist is killed off during the course of the TV movie, and the main character was Neil Tannahill, played by Trevor Eve, who at the conclusion of the story sets up a new Doomwatch group to pursue the same aims as that of the original series. In the film, an artificial black hole is created as an energy source. The downside of this was, once created, it must be forever looked after or it could explode with force enough to destroy a country. Although Channel 5 had intended the production to act as the pilot for a possible series and it had been generally well received by critics and public, further episodes were not forthcoming. This was generally accepted to be for reasons of cost. VHS and DVD releases BBC Enterprises released two separate VHS tapes in March 1991, the first containing "The Plastic Eaters"
