The Diamond Trap has two things going for it: the presence of the avuncular Howard Hesseman in the lead role and some decent location footage shot in and around London, an unusual luxury for a made-for-TV film. Unfortunately the film is also saddled with a truly wretched performance by Brooke Shields, whose attempts at an English accent are quite bizarre. Nothing special, but if you can overlook Ms. Shields, an acceptable way to kill 90 minutes.
