When Damien (Reed Diamond) meets the Duke of Weddington (Kevin McKidd), he quips that the Duke looks very familiar. This is a little easter-egg for viewers who have also watched the show Journeyman in which Diamond and McKidd played brothers.
Towards end of the episode, a shot taken in the Malibu beachhouse shows a poster on wall of A Clockwork Orange.The lead character in the film was played by Malcolm McDowell who plays Stanton Infeld
Peter learns Charlie previously dated rock star Richie Sambora (of the band Bon Jovi). In real life, Sambora is the ex-husband of co-star Heather Locklear.
Goof: Damien says "INS is not in the business of simply blessing marriages." While he is correct that immigration authorities don't simply rubber stamp marriages of convenience, he has the agency's acronym wrong. The Immigration & Naturalization Service (INS) ceased to exist in 2003. These days, the agency that evaluates fiancee visa applications is called US Citizenship and Immigration Services (USCIS.)
While discussing the movie "2001: A Space Odyssey", Stanton Infeld says: "I love that director",referring to Stanley Kubrick. Malcolm McDowell starred in Kubrick's next film after "2001", "A Clockwork Orange".
