The 30-year-old Blue Valentine star, who is also starring in All Good Things, said that he tries to limit his work because he fears over-exposure.
He told the Los Angeles Times, 'I try not to make too many movies. I get sick of myself, so I can imagine how everyone else feels. And for the two to come out at the same time, it makes me feel sick.'
He added that he also hates being asked about his motives for being a movie star, because acting is simply a 'compulsion' for him.
'I don't really like doing interviews because I don't have any answers about why I act,' he explained.
