Rod Hallett Joins Cast of Terra Nova

Rod Hallett will soon be going back in time.

The British actor, best known for his work on The Tudors, has been cast in a regular role on Terra Nova, Fox's new, prehistorical-based drama.

Terra Nova centers on Jason O'Mara as Jim Shannon, who time travels to the dinosaur era in order to save the human race. Hallett will portray Jim's nemesis, a doctor who vies for Shannon's wife's affection.

The show will air Mondays at 8 p.m. this fall.
