This film adapted from the Neil Simon play and spawning an award-winning TV show, is great in its own right. In probably their greatest and most hilarious pairing, Jack Lemmon and Walter Matthau are Felix Ungar and Oscar Madison respectively. Both men are divorced and after Felix almost commits suicide, Oscar allows his friend to live with him. Felix is a neat freak and Oscar is a slob creating conflict and many comedic moments along the way. Besides the main stars who are great, their poker playing buddies add to the humor. To round out the film there is the fantastic theme song which you cannot help from humming. Not to mention the comical Pigeon sisters either. There is no denying that this is a very funny film.
