The Shallows (2016)

Stranded on a rock just a few hundred yards from a secluded beach, surfer Nancy Adams (Blake Lively) faces a battle to survive a great white shark circling her.

Directed by Jaume Collet-Serra, the film is a masterclass in survival suspense. Lively’s strong, physical performance as Nancy carries the film, as she tries to flee the man-eater.
