The Odd Couple is a play by Neil Simon. Following its premiere on Broadway in 1965, the characters were revived in a successful 1968 film and 1970s television series, as well as several other derivative works and spin-offs. The plot concerns two mismatched roommates: the neat, uptight Felix Ungar and the slovenly, easygoing Oscar Madison. Simon adapted the play in 1985 to feature a pair of female roommates (Florence Ungar and Olive Madison) in The Female Odd Couple. An updated version of the 1965 show appeared in 2002 with the title Oscar and Felix: A New Look at the Odd Couple. Source: Wikipedia (en)
