Every movie star everywhere is quitting! In today's case of old Clint Eastwood it makes sense, because he's, y'know, old and his directing career has been a lot more illustrious than his acting career has for the past decade or so. But the once-promising, now-squandered Joaquin Phoenix? Baby mill Angelina Jolie? Nicole Kidman?? If they leave, then what are we to do? Find new movie stars, I guess. Trouble is, there aren't really any good, young understudies waiting in the wings. But there might be some! We'll take a look at who could replace these four retiring (or maybe semi-retiring) actors after the jump.
