Although it’s been running in theatres for quite a while, the first teaser trailer for Alexandre Aja’s Piranha 3D has only just shown up online. A remake/reimagining of the 1978 horror film, Piranha 3D features a group of people enjoying themselves in Lake Victoria when a tremor unleashes a pack of prehistoric killer fish, who like nothing more than chomping on human flesh. The movie stars Elisabeth Shue, Christopher Lloyd, Jerry O’Connell, Kelly Brook and Ving Rhames, and just to make sure you don’t forget the grandaddy of murderous fish tales – Jaws – Richard Dreyfuss pops up too. Click below to take a look at the teaser trailer. Piranha 3D is due out on August 20th.
