King Crab Attack! is a seven minute long French film. Here is 36 seconds worth of trailer, which is dubbed in English.

The film is basically about transgenic giant crabs that attack the beaches of Trouville. The evil Raymond Santos, owner of a nearby processing plant, seeks to increase his company’s profitability by mucking about with the genetic structure of ordinary crabs, which proceed to do what all good self-respecting critters do in those circumstances: they grow to an enormous size and go on a rampage of destruction.
