Gregory Peck and Laurence Olivier are excellent actors (examples are in "The Big Country" and "Spartacus" respectively), the producer, Martin Richards, went on to win an academy award for "Chicago", and the idea of this movie has great potential (cloning Adolf Hitler rather than dinosaurs, as in "Jurassic Park"), but somehow the combination fails miserably. The two leads indulge in completely over-the-top acting, which made me want to cringe. I've given it five out of ten for the story.
