The main problem with this 1980 science fiction drama is that it is oh-so derivative. However, it is classier than your average Wolf Man rip-off, as Ken Russell directed it and the screenplay it is based on the 1978 novel by Paddy Chayefsky. However, Chayefsky so disliked the finished version of the film, with its preposterous ending, that he asked to have his name removed, with the credit for the screenplay attributed to his pseudonym, Sidney Aaron.
William Hurt, in his screen debut, plays the mad scientist who develops a kind of think tank that regresses him to a primal state. In other words, he enters a meek scientist, but emerges a hairy ape. The film's pacing is part of the problem, as it talks us to death in the beginning, than lapses into more typical fare, disregarding the intellectual aspects of the original material. This film marks the screen debut of Drew Barrymore. --Rochelle O'Gorman
