Which was made into the Will Smith movie I am Bored.
Saw part of the Will Smith one on TV, only the first few minutes. I believe Matheson’s book I Am Legend (which I did read years ago) was made into movies with diff titles (Omega Man, Charlton Heston; Last Man on Earth, Vincent Price?) before the Will Smith one went with the orig book title.
(Same thing with some other films; Roald Dahl’s Charlie and the Chocolate Factory was made as Willy Wonka... (etc) with Gene Wilder, but went to orig title with the Johnny Depp version)
