Alternate versions

On the 25th Anniversary Blu-ray and DVD, a brief musical cue is missing from the soundtrack. In previous versions, the reveal of Beta's half-formed face as he pulls the bed covers away (about a half-hour into the film) is accompanied by a string/cymbal crescendo, followed by a loud, low brass/percussion sting, which then crescendos into the next scene. This cue is completely absent on the 25th Anniversary Edition (though it is audible on the commentary track).

In the 1998 VHS release of the film in Australia and New Zealand, both the Universal Pictures and the Lorimar logos were replaced by the Warner Brothers logo at the beginning of the film.

Beta-Alex pulling the bed cover away revealing his half-formed face was missing in the 1987 ITV broadcast in the UK.

The version that aired on CBS-TV in the late 1980s had several small edits for time and content, but it also uniquely contained a brief music cue during the opening Universal and Lorimar logos (the same cue that later accompanies the introduction of the Frontier). In most releases of the film, the logos are silent.
