Esai Morales has a rival in "Caprica."
Set 50 years before "BSG," "Caprica" follows two rival families -- the Graystones and the Adamas -- as they grow, compete, and thrive in the vibrant world of the 12 Colonies.
Stoltz will play wealthy computer engineer Daniel Graystone, who, after a family tragedy, creates something technologically amazing that will change the future of Caprica. Could it be a Cylon? Toressani will portray his daughter Zoe.
Morales was previously cast as the ruthless Joseph Adama, the father of William Adama, the future admiral of Battlestar Galactica. Paula Malcomson was also announced to play a surgeon who works as a double agent.
In other Sci Fi casting news, Frances Fisher will appear in an eight-episode guest arc for "Eureka," playing Samantha Thorne, aka "the Fixer," a corporate titan who is brought in to clean up Global Dynamics. The show returns to the network for its third season on July 29.
