Dimension Films has released the third trailer for Piranha 3DD, which brings more blood and carnage to theaters June 1. Ving Rhames, Christopher Lloyd, and Paul Scheer return from 2010's Piranha 3D, but there are several new cast additions such as Danielle Panabaker, Katrina Bowden, and David Hasselhoff, who plays himself. This "revised" trailer includes new footage of The Hoff, and we also have a photo of the former Baywatch star manning his new lifeguard post. Check it out.
