[jus_the_facts]

I Am Legend has been adapted to a feature-length film three times. The book has also been adapted into a graphic novel titled Richard Matheson's I Am Legend by Steve Niles and Elman Brown.<10>

A nine-part reading of the novel performed by Angus McInnes was originally broadcast on BBC Radio 4.<11>


The Last Man on Earth

In 1964, Vincent Price starred as Dr. Robert Morgan (rather than "Neville") in The Last Man on Earth (the original title of this Italian production was L'Ultimo Uomo Della Terra). Matheson wrote the screenplay for this adaptation, but later rewrites were changed because he did not wish his name to appear in the credits; as a result, Matheson is credited under the pseudonym "Logan Swanson."


The Omega Man
Main article: The Omega Man
In 1971, a far different version appeared as The Omega Man, starring Charlton Heston (as Robert Neville) and Anthony Zerbe. Matheson had no influence on the screenplay for this film; it deviates from the novel's story in several ways, completely removing the vampirical elements.


I Am Legend
Main article: I Am Legend (film)
Will Smith stars in the film directed by Francis Lawrence, released on December 14, 2007. This movie also deviates vastly from the original novel, as there are "mutants" instead of vampires and the still living are removed entirely.
