47 Meters Down

47 Meters Down stars Mandy Moore and Claire Holt as two sisters who go vacationing in Mexico. They decide to go see some sharks...and that's when the screaming begins.

The sisters are protected from the sharks by a shark cage. But the shark cage falls to the bottom of the ocean, trapping the girls with only an hour's worth of air and surrounded by hungry sharks.

While Moore and Holt wear diving gear, they don't wear flippers--instead they go barefoot throughout their underwater ordeal (which lasts for the better part of the film's running time).

47 Meters Down is a fun, scary flick that might be enjoyable for Halloween. They made a sequel, 47 Meters Down: Uncaged. I haven't seen the sequel yet.

It would serve as a nice double with the recent Crawl.
