The world premiere of Water For Elephants was the place to be in NYC last night. Robert Pattinson and Reese Witherspoon were the stars of the red carpet with Reese stepping out in a sexy white Jason Wu dress and Rob bringing his hotness in a suit. Christoph Waltz was on hand and we chatted with him on his way into the screening. He told us that he didn't have a lot of involvement with the animals on set and that he hadn't read the book before being asked to work on the project. The actor who portrays Rob's character as he ages, Hal Holbrook, also stopped by to talk about the movie, saying that he was excited to be involved and that the younger ladies in his life were all thrilled when they found out he'd be working with Rob. Also making appearances on the scene were Julia Stiles, Gina Gershon, and the author of the best-selling book, Sara Gruen. We also snagged a moment with Rob and Reese, with both stars revealing the reason they decided to work on the film — stay tuned for highlights from the big event!
