LOS ANGELES: US science-fiction author Richard Matheson, whose novels and stories were adapted for the big screen and television, has died aged 87. A spokesman for the Academy of Science Fiction, Fantasy and Horror Films said he died on Sunday in Los Angeles. He is survived by his wife and four children. Matheson’s 1954 horror novel I Am Legend was adapted three times as a film, most recently in 2007 as a big-budget thriller starring Will Smith. It is considered a landmark work in the genre, ushering in zombies and apocalyptic themes to post-World War Two America.–WO
