Re: Continuum the new tv series!
Credits are about money. If an actor gets credited in the main titles for an episode, that means he gets paid for that episode and gets residuals from its reruns and home-video sales, whether he appears in the episode or not.
That must depend on the show, then, or the rules have changed in recent years. But take Babylon 5
as an example: most of the cast weren't contracted and paid for all 22 episodes (some were contracted for as few as 13), but they didn't have to change the main titles for every episode.
