I know The Expanse has almost exclusively cast relatively unknown actors but who would you cast for large characters we haven’t seen in the show?
Edit: I’m all for casting (relatively) unknown actors, by the way. Just thought it would be fun speculating which better known names would fit some characters :)
The name “The Expanse” is what’s going to bring in the fans.
Use unknowns for all the roles. It gives good actors a chance to be seen, and viewers aren’t distracted by familiar faces.
