Something worse than snake bite

Working with snakes can be more hazardous than you thought -- but it's not their bite that's the problem.

"It's the poop," Jules Sylvester, head animal trainer for the new Hollywood movie "Snakes on a Plane" said Monday at a news conference to publicize the film.

"They will poop everywhere," he added.

But when snakes are on a movie set, everyone behaves, Sylvester said.

"It's ideal for the director," he said.

The movie, starring about 500 snakes and Samuel L. Jackson, opens in U.S. theaters Friday after receiving wide publicity on the Internet.
