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.

Steven Spielberg revealed he's developing a western film and discussed his upcoming film 'Disclosure Day' — plus Obama's recent comments about aliens.

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