'Battlestar' actor cast in 'Eureka'

Battlestar Galactica's James Callis has joined the cast of Eureka, according to The Hollywood Reporter.

The actor, famous for playing Dr. Gaius Baltar, will appear on Eureka's upcoming fourth season as the mysterious Dr. Grant.

His character, whose return to his hometown raises alarm, will cause friction when he takes a romantic interest in Allison Blake.

Callis has previously appeared on Numb3rs and will guest star on ABC's FlashForward when the series resumes later this month.
