Natalie Portman may still do action movies in the future, but maybe no more green-screen work. Between Lucasfilm and Disney/Marvel, I think she's had more than enough. No WWE or UFC in her future, but she may still have sufficient box-office pull for either. She's still an actress in the truest sense of the word, not simply a movie star.
When Doctor Who made its major comeback, Christopher Eccleston was the 9th Doctor. He was the one who dressed in black leather, like a short-haired Duncan MacLeod. He only lasted 1 season, to be followed by David Tenant; I have no idea why he only lasted 1 season. Besides his turn as the 9th Doctor, and Malekith in Thor 2, he was Destro in the G. I. Joe movie featuring both Channing Tatum and Sienna Miller.
It looks as if both Christopher Eccleston and Christian Bale fell behind on their bills and needed some extra cash flow. Sooner or later, all the big-name actors (including Robert DeNiro) end up in that situation.
