The Colony

"The Colony" is a sci-fi film starring Laurence Fishburne. It's set in the near future, on an Earth that has entered a new Ice Age. The last remaining humans survive in isolated colonies that are dying off of disease and starvation, but a new threat has emerged: a crazy, psychotic cannibal tribe. It's a better movie than it sounds in this description, and it features one of the goriest, wickedest final fight scenes around. Rent it!
