Introduction by the author (Ray Bradbury), who looks around into a crammed room for an object which will inspire him.
A renown producer called Joe Clarence (Jim Dunk) which happens to have a huge piece of bone protruding from his head covered by skin complains to the stop-animation man Terwilliger (Cris Campion) that the dinosaur he's creating won't scare anybody. The technician finds his work rejected once and again, until finally he decides to put the same bone in his dinosaur. The producer gets angry at first, but then his assistant, called Glass (Daniel Ceccaldi) convinces him that it was all done out of admiration for him, and that he'll become famous. A niece (Julie Reitzman) of the assistant and his friends ask him for autographs pushed by her uncle, while the producer's fake fame goes to his head and he starts roaring like a dinosaur.
