We caught up with Robert Pattinson Friday at the Breaking Dawn Part 1 junket in Beverly Hills, where he joined forces with Kristen Stewart, Taylor Lautner, and several of their castmates to begin promoting the film. The highly anticipated fourth installment in the Twilight franchise opens on Nov. 18, and Robert told us he wasn't immune to the pressure to live up to the fans' expectations. In fact, he said he was especially apprehensive about the birth! Rob gave us some behind-the-scenes scoop on how they filmed that gory scene, recounted a moment in the film where Bella tries to tempt Edward with a lingerie fashion show, and even responded to a Twitter account set up in his dog Bear's name. Check out our interview with Rob!
