For TV’s biggest stars, key roles on successful shows mean huge paychecks — but the payoff doesn’t stop there. When shows are syndicated, redistributed, released on DVD, purchased by a streaming service or otherwise used beyond what the actors were originally paid for, those actors get residual checks called royalties.

So, do all actors get paid for reruns? According to the Screen Actors Guild-American Federation of Television and Radio Artists, some do and some don’t. For principal performers, royalties can lead to long-term payoffs that trump the original salary. Background actors, on the other hand, won’t be getting any residual checks in the mail.
