Oscar Madison: A slovenly, recently divorced sportswriter.
Felix Ungar: A fastidious, hypochondriac news-writer (photographer in the television series) whose marriage is ending.
Murray: A NYPD policeman, one of Oscar and Felix’s poker buddies. Very ‘straight up’
Speed: One of the poker buddies. Gruff and sarcastic, often picking on Vinnie and Murray.
Vinnie: One of the poker buddies. Vinnie is mild-mannered and henpecked, making him an easy target for Speed’s verbal barbs.
Roy: One of the poker buddies. Oscar’s accountant. Roy has a dry wit but less cutting than Speed.
Cecily and Gwendolyn Pigeon: Oscar and Felix’s upstairs neighbors, a pair of English sisters. The former is a divorcée, the latter a widow.
All the men are around 40 years old, give or take a few years.
The women approximately 30 years.
