The Descent (2005)

In The Descent, six women go spelunking in an uncharted cave system and find physical (and emotional) horrors heretofore unknown. The story is first rate and the six actresses (Shauna Macdonald, Natalie Mendoza, Alex Reid, Saskia Mulder, MyAnna Buring and Nora Jane Noone) are bad-ass. Director Neil Marshall has created a bloody and claustrophobic (really claustrophobic) exercise in terror that never lets up.
