When I first saw this film years and years ago, I thought it was really good and amusing, apart from the two girls who come downstairs from their flat on a date with the two men. The girls irritated me with their stupid giggles and conversation, but I still enjoyed the film.
Oscar (Walter Mattheau) is a sports journalist and slob who lives happily in his messy apartment until he invites his friend Felix (who has just been dumped by his wife)to stay with him. Felix swiftly drives Oscar mad with his obsessive cleaning and tidying, and he even manages to ruin their weekly poker game. The last straw comes when Felix ruins the romantic liaison that Oscar has planned for them with their neighbours the Pigeon sisters.
This is a very funny film, Walter Mattheau and Jack Lemmon are both hilarious, and the supporting players all have their moments too. I love this film not just because it is very funny, but also because it reminds me of my husband and I (him being Felix and me Oscar).
