Piranha 3D (Blu-ray 3D)

Includes both anaglyphic (requiring the use of the included 3D glasses) and stereoscopic (for 3DTVs & blu-ray players) 3D versions of the film, as well as a 2D version. 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.
