Paul Campbell (Billy Keikeya) almost left
Battlestar Galactica (2004) after the end of
Season One since he wasn't under contract. After his new show didn't
work out, he returned for Season Two. The producers asked him to sign a
five-year contract. He didn't respond and the producers sensed he
wasn't committed to the show. They couldn't write long-term story arcs
because they didn't know if Campbell would be available. Thus, they
decided to kill off Billy, according to Campbell. Though he appreciates
quality TV shows, he is not a science-fiction fan. It was difficult for
him to leave the show, but Campbell says it was the right
choice.
