Movies like the ωmega man

The Omega Man (stylized as The Ωmega Man) is a 1971 American post-apocalyptic action film directed by Boris Sagal and starring Charlton Heston as a survivor of a pandemic. It was written by John William Corrington and Joyce Corrington, based on the 1954 novel I Am Legend by Richard Matheson. The film's producer, Walter Seltzer, went on to work with Heston again in the dystopian science-fiction film Soylent Green in 1973.

The Omega Man is the second adaptation of Matheson's novel. The first was The Last Man on Earth (1964), which starred Vincent Price. A third adaptation, I Am Legend, starring Will Smith, was released in 2007, and "borrowed" this film's tagline.
