Dimension Films has released the U.K. poster for Piranha 3D, which stars Eli Roth, Dina Meyer, Elisabeth Shue, Jerry O'Connell and Christopher Lloyd.

Director Alexandre Aja's 3D action thriller comes to theaters August 20th.

After a sudden underwater tremor sets free scores of the prehistoric man-eating fish, an unlikely group of strangers must band together to stop themselves from becoming fish food for the area's new razor-toothed residents. But our heroine (Elisabeth Shue) is seriously outnumbered, and with only one chance to save the lake and her family from totally being devoured, she must risk everything to destroy the aquatic carnivores herself.
