Jurassic Shark (2012)

When a company drilling in a lake disturbs the lake bed, it frees a Megalodon-like prehistoric shark. A gang of art thieves hiding on an island and a pair of students who wander into their path are soon trapped together with the predator circling. Jurassic Shark is an ultra-low-budget Canadian creature feature from Brett Kelly, and it became known mostly as a so-bad-it's-fun film, enjoyed for its cheap effects and earnest acting. Viewers who like monster B-movies watched with friends will find it in that tradition.
