Levin was the Stephen King of the 1960s and 1970s. He had a knack for turning absurd plots into realistic horrors, and like King, most of Levin's major works have been made into movies. His novels include This Perfect Day, Rosemary's Baby, The Stepford Wives, A Kiss Before Dying, The Boys from Brazil, and Sliver. His plays include Deathtrap, No Time for Sergeants, Critic's Choice, Footsteps, Dr. Cook's Garden, Cantorial, and Veronica's Room. (Bio from NNDB)
Levin died from a heart attack in 2007 at the age of 78. His legacy lives on through his books and many movie adaptations.
A big inspiration on Chuck Palahniuk, Ira Levin had this to say about 'Diary':
"Just for the record, Diary is as hypnotic as a poised cobra. Chuck Palahniuk demonstrates that the most chilling special effects come not from Industrial Light and Magic but from the words of a gifted writer." - Ira Levin
