Given that this is based on a Clive Barker story, and contains some major acting talent it should be good. It's NOT good, and the blame for that rests squarely with director George Pavlou.It could have been an interesting melding of the crime/horror genre, but takes every wrong turn possible.
Larry Lamb is a good actor, but he is so hopelessly miscast here as the hard man reluctantly dragged back into the criminal underworld, that there is a gaping hole at the heart of the film where a central character should be. In fact most of the normally reliable actors here, turn in awful performances.
The sets are awful (the neon tube underground lab looks like a Gary Numan stage set). The costumes are awful (the gangsters dress like Duran Duran). The music is awful, and the dialogue is awful. The script is so bad its difficult to imagine Barker had anything to do with it. At one point "our hero" is injected with the deadly transmutating drug, absolutely nothing happens to him, its simply not referred to again !. In playing down the horror element, and playing up the crime element, the producers missed an opportunity to produce a piece of contemporary horror, and instead produced a cheap looking Mockney version of Miami Vice. Most of the people involved leave this off their c.v.'s. I'd certainly leave it off your shopping list.
