Comparison between the old German VHS (=first UK DVD release) and the uncut German DVD from 20th Century Fox.
There are 37 seconds missing in 11 scenes.
According to different sources like Melonfarmers and the German OFDB the first UK DVD releases of Predator feature the old German VHS version of the movie which had been cut in several scenes. As per Melonfarmers this concerns the UK DVD releases from 2001 and 2003. All other UK DVD releases are uncensored, including the Blu-ray release. The BBFC has nothing to do with the cuts, because the old BBFC 18 VHS had been released uncut without any censorship. Most likely it was a mistake by 20th Century Fox where they took the wrong master. Ironically the first German DVD offered the uncut version for the first time in Germany.
However: We can't say whether the old UK DVDs feature the old German VHS version or not because we do not have one of those DVDs. But what we have are the cuts of the old German VHS, which are listed in the following article.
