I don’t know why anyone would care what an actor had done before. Peter Cushing and Alec Guiness were legendary. Billy Dee Williams and Frank Oz were very well known. Samuel L. Jackson, Ewan McGregor, Natalie Portman and Liam Neeson were all stars in their own right. Woody Harleson has a wide body of work, as does Emilia Clark. Felicity Jones wasn’t exactly an unknown either. All the Star Wars films have their share of notable people in them. They are actors, they play roles. If they have solid careers, they played roles before and they will play roles after. You can’t get stuck on one performance. That isn’t how it works.
