The scene where the kids "energize" Hulk as he comes back from the shower had to be cut. The BBFC saw a too high danger of imitation by children at home. You still see what happens to him afterwards, but they removed the scenes where the trap is explained. This kind of editorial control seems to make sense and the movie - apart from its bad image quality - is still viewable.
In the UK the movie was solely released on VHS (Mr. Nanny only or in a bundle with Suburban Commando) and never appeared on DVD.
