Just a coupla dudes questioning the meaning of life. Brad Pitt appeared on The Late Show With Stephen Colbert last night and admitted that he “hasn’t been out in a while.” The duo chatted and filmed an installment of Colbert’s Big Questions With Even Bigger Stars, during which they shared a faux philosophical dialogue that poked fun at Pitt’s monster hit Fight Club. “Do you think anyone can ever truly know themselves?” Colbert asks.“Doesn’t matter,” Pitt replies. “In the end, turns out we were all Edward Norton the whole time.” Later, Colbert wonders, “Is it possible to describe infinity?” Pitt responds: “Yes it is. It’s one less than the number of Ocean’s sequels we’ll be making.” Pitt is making the rounds promoting new movie War Machine, which drops May 26th.
