This movie, Invasion: UFO was produced at the ITC's New York offices in 1980 and not 1974 as stated on IMDB. It was made by compiling several episodes. The movie was targeted at satellite and cable television services in America, and later found it's way on UK home video in 1983, the first UFO video release until Channel 5 video released the majority of the series including Invasion: UFO in 1986. The movie is comprised mainly from the three episodes 'Identified', 'Computer Affair' and 'Reflections in the Water', although it does feature some small clips from 'ESP', 'The Man Who Came Back' and 'Confetti Check A-OK'. The ITC New York Offices produced several TV movies from Gerry Anderson productions between 1980 and 1982, Stingray, Thunderbirds and Captain Scarlet were notably used, and some of these movies aren't too bad, as they were generally faithful to the original material, although the new opening titles they created for the movie were ghastly. For the opening they have taken away the original theme music and replaced it with an awful 80's sounding pop theme. They have also added further 80's sounding rubbish to the incidental soundtrack, which does not fit the action and spoils some of the fear in the proceedings. Other than this they have not changed the original material apart from the obvious editing. 3 episodes, 'Identified', 'Computer Affair' and 'Reflections in the Water' are chopped virtually in half to allow for the maximum 100 minutes running time the makers of the movie had to comply with. They were also edited on videotape which you have to adjust to if you have been watching the series on DVD, and the quality is poor compared. On the plus side, many of the linking scenes are put together well, but it is still confusing at times. George Sewell who plays Col. Alec Freeman disappears 30 minutes before the end of the movie, because he was not in the final episode used, and his absence isn't explained. Peter Gordeno who played Capt. Carlin also disappea (thetvdb.com)
