A legendary screenwriter of science fiction and horror, Dan O'Bannon, best known for writing Alien, passed away today at the age of 63. Bannon broke out back in 1974 with the lo-budget sci-fi flick Dark Star, which was director John Carpenter's first major film. O'Bannon not only wrote the script for Dark Star, he also edited, art designed, acted in, and handled the special effects on the film.
Then he wrote Alien, which would be his biggest film both critically and commercially. But oddly enough, O'Bannon's most ardent fans, while they unabashedly love Alien, seem to support the guy more for his smaller cult movies like Dark Star, Dead & Buried, Blue Thunder, his segment "B-17" in Heavy Metal, and for The Return of the Living Dead, a film he also directed.
