The opening of Charlton Heston's The Omega Man rivals even the devastating ending of Planet of the Apes. The Omega Man is the second movie adaptation of I Am Legend, the classic post-apocalyptic novel about the last man alive surviving in a world filled with vampires. In truth, the Heston version has little in common with the Richard Matheson novel, which includes replacing the vampires with mutant albinos and dropping the infamous ending. The movie was a hit back in 1971 and has since become a cult favorite; in fact, The Omega Man is one of Tim Burton's favorite movies.
