The "Alien" franchise is an undeniable classic — a staple of the sci-fi/horror genre. The series features humans fighting for their lives as they're pitted against killer aliens with acidic blood.

John Carpenter proved he could do far more than horror classics in this formulaic yet compelling 1984 film starring Jeff Bridges and Karen Allen.

Movies like Oldboy and Misery are harrowing experiences that force their characters (and us) to endure intense and scarring psychological torture.
