Author and playwright Dale Wasserman has died at age 94. Wasserman is known primarily for writing the book upon which the classic musical Man of La Mancha was based. The play, which opened in 1965, has been a perennial favorite for theater-goers around the world. It tells the story of the whimsical dreamer Don Quixote and features the famous song The Impossible Dream. Wasserman was also credited for bringing attention to writer Ken Kesey's One Flew Over the Cuckoo's Nest by adapting Kesey's book for the  original version on the New York stage in 1963. Although this production, which starred Kirk Douglas, was an initial flop, Kesey gave kudos to Wasserman's adaptation for the play's ultimate success and eventual emergence as an Oscar-winning film in 1975. Wasserman also occasionally dabbled in screenwriting with his most notable success the hit 1958 adventure The Vikings which starred Kirk Douglas and Tony Curtis. He had completed a new play shortly before his death. For more click here
