I have read five plays written by Tennessee Williams: A Streetcar Named Desire, The Glass Menagerie, Cat on a Hot Tin Roof, Orpheus Descending and Suddenly, Last Summer.
Brick Pollitt is a former football player who drinks his days away. His wife Maggie has all but failed to entice him. His father Big Daddy, dying of cancer, wants to give his plantation to Brick and Maggie, much to the dismay of Brick's brother and his wife.
Williams' play is a fine drama with excellent characters that always have you interested about them. Richard Brooks' film is well-acted and Paul Newman, Elizabeth Taylor and Burl Ives are perfectly cast in their roles. Cat on a Hot Tin Roof is one of those rare examples where the book and its film adaptation are both very well done, making it almost impossible to say which one is better.
What's worth checking out?: I'd go with both.
