Bradley Cooper joined his costars Abbie Cornish and Robert De Niro at the premiere of Limitless in NYC last night. He arrived in town after showing off the movie at a special screening in LA last week. Since then, he's taken care of promotional duties like his weekend press junket and an appearance on Inside the Actors Studio. The show's host, James Lipton, showed his support for Bradley at last night's event, where we chatted with the star on the red carpet. He touched on his intimate onscreen moments with Abbie, saying they were "technical," while she called their kissing scenes "easy" and shared her thoughts on Bradley's piercing blue eyes. The film features Bradley's character maximizing his work potential with the help of a small pill, though the actor confided he prefers to get his highs naturally. A pregnant Alyssa Milano gave a glowing review of the thriller after watching alongside Gossip Girl's Matthew Settle, Jason Bateman, and designer Rachel Roy, and the fun continued following the screening when the cast headed to Buddakan to celebrate.
