10. Black Water

From writer/directors David Nerlich and Andrew Traucki - more on him later - 2007's Black Water is an utterly brutal, basic-but-brilliant crocodile-driven feature.

Loosely based on a real tragedy, the general premise of Black Water finds lovebirds Grace and Adam, and Grace's sister Lee, embarking on a fishing trip in a mangrove swamp. When their tour guide suggests they go a little further afield once the fishes aren't biting, that's where things take a literal turn for the worse as a saltwater croc capsizes their boat.

After that tour guide is devoured by this toothy menace, our core three are caught between a rock and a hard place; either take short-term solace up a tree, or swim out to their upturned boat and make a break for safety. To compound this predicament, nobody else is aware that they've even taken this trip, daylight is slipping away, and this crocodile is very much in its natural habitat... and is very much hungry for more human flesh.

Black Water is a film that plays with your expectations, that masterfully uses the one sole location where so much of the feature takes place, that takes an extremely serious approach to its subject, and that could well be the greatest croc feature in the history of that particular subgenre.
