Sean Astin feels the rage as 'Patient Zero'

Forget all about his crying Hobbit from The Lord of the Rings — in a new horror movie, Sean Astin is way more angry than weepy.

The actor stars in Cabin Fever: Patient Zero (in theaters and on iTunes Friday), a prequel of sorts to Eli Roth's gruesome and flesh-eating 2002 horror flick Cabin Fever. Patient Zero bring the terror out of the forest and into a Caribbean paradise, where a bunch of friends on a bachelor weekend began to show symptoms of a contagious virus.

On this island, they find a mysterious research facility and a lock-in named Porter (Astin), who is a carrier of this nasty pandemic yet is also completely immune. Doctors are keeping him quarantined because they don't want him infecting the world but are experimenting on him so they can find a potential cure.

Slowly he descends into madness while in captivity and drops some knowledge in this exclusive clip about Three Blind Mice, the children's nursery rhyme that Porter says was really inspired by the wrongful imprisonment, torture and execution of three protestants by England's Queen Mary I in the 1500s.

Another fun fact: Patient Zero director Kaare Andrews is the writer and artist of Marvel Comics' Iron Fist: The Living Weapon comic book. In addition to Astin, his Cabin Fever cast includes Ryan Donowho, Brando Eaton, Jillian Murray, Mitch Ryan, Lydia Hearst and Currie Graham.
