Alternate versions

Regrettably, the 20th anniversary restoration recently screened at Paramount used the DVD version, thus it goes from 1.37 to 2.35, including the 20 minutes or so that are supposed to be shown at 1.85.

The theatrical version was screened at three different aspect ratios: the early scenes, featuring clips of the TV series, were shown at 1.33:1; the initial part of the story, set on Earth, was framed at 1.85:1; the scenes set in outer space were screened at 2.35:1. The DVD release keeps only the initial 1.33:1 full frame scenes, then shows the rest of the film at the wider aspect ratio of 2.35:1. This was done on purpose because director Dean Parisot felt it played better on home video screens.

Deleted scenes included on the DVD:

• Tech Sargeant Chen helps an engineering crew solve a difficult problem without offering any insightful help whatsoever.
• Alexander is presented his living quarters: an empty room save a bed of spikes and a daunting toilet.
• An alternate version of a scene in which its revealed Jason and Gwen were old flames.
• Guy overreacts when his foot gets caught in a rock, and Jason does his "rugged pose".
• Alexander uses an acting method to figure out the rock monster's "motivation".
• Gwen rips open her uniform to seduce two enemy soldiers, before crushing them with a door. (Part of this scene was featured in the trailer.)
• General Sarris revives himself and attacks the crew while crash landing.

The Region 1 DVD release includes an alien soundtrack option, that allows viewers to watch the movie dubbed into the strange alien language used in the movie.
