Aliens

Like most films, the movie wasn't shot in sequence. But for added realism, James Cameron filmed the scene where we first meet the Colonial Marines (one of the earliest scenes) last. This was so that the camaraderie of the Marines was realistic because the actors had spent months filming together.

(at around 2h 10 mins) When Bishop saves Newt from being sucked out of the airlock, part of Lance Henriksen's real torso can be seen beneath the false one, emerging from a hole in the floor. (James Cameron acknowledges this error on the DVD commentary; the goof was digitally corrected for the 2010 Blu-ray release.)

As the final credits fade, there is the sound of an alien egg opening.

The Finnish VHS version rated K16 is cut with 3 minutes and 42 seconds. Some gory murders done by the aliens, some acid-to-the-face scenes, and pretty oddly the entire "fingers and knife"-game between the soldier and Bishop, and just a shot of Newt in the water and couple of aliens rising up to the surface, are cut out. The scene in the movie's ending, where the alien queen rips Bishop in half is heavily cut too. The Finnish video version re-release is still heavily cut (3 minutes and 3 seconds), although it's a little more complete (at least the "fingers and knife"-game is intact). The cuts on both versions were applied by the distributor.
