Cadillacs and Dinosaurs is a TV series that aired from 1993 – 1994. The plot involved the adventures of Jack Tenrec, a garage mechanic. His greatest passion in life was restoring classic cars, especially Cadillacs. His side kick is Hannah Dundee, a foreign ambassador. She hires Jack to be the liaison in helping to communicate between her land and modern civilization. While they do this, they keep running into some serious confrontations involving a futuristic world where humans and dinosaurs co-exist. This world seems to be in ruins.
Other characters include Hermes, who is a juvenile Allosarus that Jack raised by hand, and the villain Wilhelmina Scharnhorst, who has an army of henchmen. Hermes, while gentle and affectionate with Jack and Hannah, could become highly enraged and dangerous to anyone or anything that threatened the two of them. The question of how the dinosaurs, that were thought to be extinct, were re-born was never fully answered in the series.
The show, dealing with political and ecological issues, lasted one full season of 13 episodes. It was never even considered for renewal.
