Robert Pattinson and Sean Penn's Super Team-Up?

New Moon and newly single actors in talks to join Reese Witherspoon in Water for Elephants

Robert Pattinson's brought plenty of dough to movie theaters, so why not bring Water for Elephants?

Now the New Moon hottie is, per Variety, in talks to join Reese Witherspoon in the adaptation of Sara Gruen's best-selling novel about a circus veterinarian during the Great Depression. Producers are also wooing Sean Penn for a spot in the Benzini Brothers Most Spectacular Show on Earth, but a source close to the actor says the Oscar winner has not committed to the project.

I Am Legend's Francis Lawrence is attached to direct the Fox 3000 feature.
