Dimension Films has premiered the first teaser for the horror sequel Piranha 3DD [PIRA2] on Spike's Scream Awards last night. The first film reveled in its exploitative fun, and the sequel looks to continue the trend. The flesh-eating school of killer fish have invaded a water park and no bare skin is safe, especially those with DD. Christopher Lloyd returns as the scientist along with Ving Rhames [VRHAM], who lost his legs in Piranha 3D and now sports prosthetic guns borrowed from Planet Terror. Joining the festivities is David Hasselhoff playing himself. Original set to open this Thanksgiving, Dimension has pushed back the release date to 2012.
