According to The Hollywood Reporter, the Universal Media Studios project is a prequel to the network's Battlestar Galactica. Morales will play Joseph Adama, the father of William Adama (played in "Galactica" by Edward James Olmos), who one day will take command of the Battlestar Galactica.

Joseph is described as a deeply passionate man with a strong sense of justice -- and someone you wouldn't want as your enemy.
