Reese Witherspoon, who recently wrapped Water For Elephants with co-star Robert Pattinson, is already moving on to her next project.

Reese is set to begin filming This Means War, a movie about two lifelong best friends who wage an epic battle against one another after they both fall in love with the same woman, in Vancouver on September 13.

Tom Hardy and Chris Pine will co-star in the movie, which is being produced by Will Smith, but don’t expect to see too much of Will in Vancity, since he sill start filming Men In Black 3 in New York City on the same day.

This Means War is scheduled to shoot though December 1.
