Black Water

Diana Glenn and Maeve Dermody star in Black Water, an Australian film about friends who get attacked by a crocodile while vacationing in a flooded mangrove field.

When their boat gets overturned by the croc, these women (along with a guy) retreat to the branches of the trees.

They go barefoot pretty much throughout the film as they try to outsmart the crocs swimming in the water below them.

If you go looking for this--and the movie overall is well worth your time--be sure to search for Black Water; the title is two words.

This would make a great double feature with Crawl, since both movies involve crocodiles chasing barefoot women.
