Third time's a charm! Back in March, MTV News sat down for a 30-minute live chat with Robert Pattinson after the star introduced an exclusive "Water for Elephants" clip. Then we met up with the 24-year-old star again at the "WFE" press day for another extended conversation about everything from "Breaking Dawn" to his favorite TV shows. Now, for the third time in less than a month, we'll once again be talking to Pattinson — and we'll be bringing the interview to you live on MTV.com.

At this Sunday's "Water for Elephants" red-carpet premiere at the Ziegfeld Theatre in New York City on Sunday, at 5 p.m. ET, host Josh Horowitz will not only be chatting with Pattinson but with Reese Witherspoon, Christoph Waltz, Hal Holbrook, Ken Foree, Donna Scott, director Francis Lawrence, best-selling author Sara Gruen, and other celebrity guests.

And you'll have a chance to submit questions for Pattinson and his co-stars. Questions can be submitted on MTV.com or via Twitter, using @MTVNews and the hashtag #AskWFE.

Based on Gruen's acclaimed novel, the film follows a veterinary school student named Jacob (Pattinson), who joins a circus around the time of the Great Depression and falls in love with star performer Marlena (Reese Witherspoon). Marlena, however, is married to a charismatic but cruel animal trainer named August (Christoph Waltz), a man who stands dangerously in the way of Jacob and Marlena's pursuit of lasting love.

"It felt like it was kind of magical in many ways, because we were out in the desert shooting," Pattinson said of the production. "There was nothing from the modern world around. It was a different experience for me. It wasn't in a studio or anything."
