10 Actors Who Appeared In Star Trek AND Star Wars

10. Greg Grunberg

Grunberg is another actor on this list who can thank JJ Abrams for much of his success. He was originally cast on Abrams' show Felicity, and they have remained working together since.

He, like Simon Pegg, appeared in Star Trek (in a voice only role as Kirk's uncle) and then appeared on-screen in Star Trek Beyond. He would also then go on to appear in Star Wars: The Rise of Skywalker, as Temin Wexley.

That is not to say that his career only features collaborations with JJ Abrams. He has a vast credit page with many voice and face acting parts to his name, even if he has a successful relationship with Abrams!
