Period pieces are the best, especially when they involve Robert Pattinson in tight pants and suspenders! Yum!

We are beyond excited that one of or favorite books is finally hitting the big screen! Water For Elephants has been on the New York Times best-seller list for over two years, so getting to see the book come alive will be such a treat!

The movie centers around a veterinary student (Pattinson) who abandons his studies after his parents are killed, and joins a traveling circus as their vet in the 1930's. We really can't wait to see the on-screen chemistry between Robert and Reese! They sure look steamy!

Check out Witherspoon's amazing moves with that white horse, we wonder how long it took to learn that? Acting with animals has got to be quite a challenge, especially when they are that size!

Water For Elephants hits theaters nationwide April 15, 2011, so until then, check out our behind the scenes photos of the sexy pair!
