Fratelli, amori e tanti guai (2007)

Sam and Gray are such a well-matched pair that it is difficult to believe they are brother and sister rather than husband and wife. They both share a love of 1940s movies and dancing, and when they meet Charlie, they have something else in common: They both fall in love with her. Sam must deal with unexpected feelings of jealousy, while Gray struggles to come to terms with her sexual orientation.
