Alternate versions

The German version has a different, happy, ending,

The 2003 German DVD release from Marketing Films includes 3 scenes which were claimed at the time to have only appeared in the German version of the film.... 1. A brief scene of Mrs Goodman saying "I'm coming, I'm coming" as she opens the door to reveal the giant Action Man. 2. Extended dialogue during the scene where Joe talks to his budgerigar at his photography studio. 3. An entire scene where Rachel & Sam visit their old house (the site of the abduction). Rachel enters the house alone and states that "Someone has been here", before opening the window to remove the smell of gas. The dialogue is in German only on the DVD and selecting the UK/US Version option simply eliminated the entire scenes. However all UK video releases included the scenes in full, despite claims that they were exclusive to the German version of the film. The UK Film 2000 DVD release misses the scenes out completely and appears to have been taken from the cut German print.

The 2018 UK blu ray release includes 4 versions of the film:- The original version The version with the alternate ending The version that was used for the original UK video release A new edit of the film from Harry Bromley-Davenport where many of the visuals have been edited

The UK cinema release had a totally different ending to the version released onto video. Following the scene where the "alien" Sam takes his son up into the spacecraft, the cinema ending shows Bernice arriving home to find the house filled with exact doubles of her son (which have presumably hatched from the eggs shown earlier in the film) which all say "mummy" as she enters the room. The video release however shows her arriving home to find the bathroom full of the aforementioned alien eggs. As she goes to have a closer look, one cracks open and an alien "sucker" device (same as the one that came out of the Alien who attacked the blonde woman in the cottage near the beginning of the film) bursts out off the egg and clamps over her mouth. The cinema (happy ending) version has also been shown on the UK sci-fi channel.
