In a version commonly shown on American television for a 2-hours-with-commercials time slot, all shots of the Predator's naked face and all instances of the Predator mimicking human speech are removed. The corresponding scenes are *not* removed for Predator 2.
In the 3D re-release the old 20th Century Fox logo is replaced with the new 20th Century Fox logo that was used in Turbo (2013).
In the 1991 ITV broadcast of the film, some violent scenes and bad language were cut for censorship and for time: Mac warning Dillon that he'll bleed him, if he gives up his position again. The decapitation of Dillon's right arm and his demise. The Predator ripping out Billy's skull and spine and Dutch calling the Predator "You One Ugly Motherfucker!" when The Predator removes it's mask.
There is a sanitised version which has most of the gory parts removed, e.g. the skinned bodies, the alien with Billy's body, Mac's brains being blown out, Dillon's arm being shot off, etc.
A limited edition DVD collector's box set of Predator including both Predator movies was released in the UK in June 2001. For this UK DVD releases, Fox used the same master as the heavily censored German version. Ironically, it was released uncut in Germany. The scene where Dutch throws a knife at the soldier and saying "Stick around" was removed. The scene where Dillon loses his arm was shortened. However, the UK video is completely uncut.
Featured on the Special Edition DVD, there is a deleted scene where Dutch is running from the predator, from tree to tree while the Predator purposely misses him
The Special edition also features three short outtakes: Anna picking up and holding a chameleon; a butterfly landing on the invisible predator's leg leaving an image of itself on it after flying away; and more footage of Dutch preparing himself before the battle with the predator
The Australian DVD release in February 2002 removed the shot where Dutch throws a knife into a soldier and says "stick around". However, in November 2002, a 2-disc special edition was released with the scene intact.
After its theatrical release the film was indexed in Germany by the BPjS (now BPjM) meaning serious business restrictions for the uncut version, such as no advertisement, no mail order and no display in showrooms accessible to minors (however, the movie may be sold in such showrooms if adult buyers specifically ask for it). Therefore the television version and the video version had some major cuts. Almost every violent scene was shortened, some scenes were completely removed (eg the scene where Dillons arm is 'removed'). The DVD was released uncut without a FSK rating but with a SPIO/JK approval. Only in 2010 the film was removed from the index and re-rated "Not under 16" by the FSK.
The Spanish language TV version includes nearly all the violence cut from other TV versions, removing only two shots: the murder of the hostage in the rebel camp and Dillon's severed arm on the ground. However, some dialogue scenes are not shown. The entire chopper ride into the jungle is removed, as well as Hawkins' joke with Billy and the subsequent shot of the Predator listening to Billy laugh. Likewise, when Mac takes the scorpion off Dillon's back, the scene ends before Mac steps on it and the Predator is not shown picking it up.
