Deep Blue Sea

Deep Blue Sea is a 1999 American science fiction horror film directed by Renny Harlin. It stars Saffron Burrows, Thomas Jane, Samuel L. Jackson, Michael Rapaport, and rapper LL Cool J. Set in an isolated underwater facility, the film follows a team of scientists and their research on mako sharks to help fight Alzheimer's disease. The situation plunges into chaos when multiple genetically engineered sharks go on a rampage and flood the facility.

This movie is always, I repeat, always broadcasted on UK television, I mean literally several days in a row. The plot of the film is silly beyond belief and some of the performances are laughably bad but it's decent for a shark movie. It has some thrilling and intense moments and is enjoyable even on rewatch. It's clear the Meg from last year took some ideas from the film also.
