Truly the most fun I had last summer at the movies was watching Piranha, which is out this week on Blu-ray and DVD and in a special new 3D version. Directed by Alexandre Aja (who made the harrowing Haute Tension), it's about an earthquake that releases schools of razor-teethed prehistoric fishes -- just in time for Spring Break. Jake (Steven R. McQueen -- yes, the grandson of the famous movie star) plays the sweet-faced son of the sheriff (Elisabeth Shue) who is hired by the vulgar Girls Gone Wild-type producer (Jerry O'Connell) to be location manager for his bodacious new video shoot. But the movie exists for the major attacks by the 3D fish and some over-the-top grisly special effects. Richard Dreyfuss shows up in a funny nod to Jaws, and Eli Roth meets a gruesome end after hosting a wet T-shirt contest. Now you can watch it in the comfort of your living room on DVD or Blu-ray with deleted scenes and commentary by the director. True, I miss the 3D penis spit up by a prehistoric piranha in my face in the movie theater, but the disc looks great and I can't wait to show it to friends.
