Jeremy Renner was all smiles last night at the premiere of The Bourne Legacy, and he was quite happy to chat with Vulture about taking over the franchise that Matt Damon used to topline. Did the responsibility freak him out? Quite the contrary! "It's been the most fun I've had on two feet in a long time," he told us. "It's like getting a ticket to a secret ride at Disneyland that no one else gets! Are you a fan of the movies? Well, so am I. So you'd be a jackass not to take that ticket and give it a go." Speaking of secrets ... what can we make of those rumors that Renner is circling a new movie where he'd play WikiLeaks founder Julian Assange for director Bill Condon? Is he ready to take on Assange's swoopy, peroxide-blond hairdo? "You're assuming that all that happens!" Renner laughed. "It's a long road to happen with that, and the content is interesting, but other than that, I couldn't tell you the reality of it. And the hair is the last thing on my mind when it comes to playing a character!" Noted.
