There are two instances of switched music between the UK and US versions of the film. In the UK version, the montage introducing the office Christmas party is set to "Too Lost in You" by Sugababes, while the US version of the film replaces it with "The Trouble With Love Is", performed by Kelly Clarkson. Then, during the second half of the end credits after the Clarkson song plays (for the second time in the US version) the UK version concludes with a cover of "Jump (For My Love)", performed by Girls Aloud. This song does not appear at all in the US version, which concludes with the Sugababes song that the UK version used at the party. The 2009 US Blu-Ray actually contains the UK cut of the film, while the original US DVD had the US cut.
Asian releases (except for Japan and The Philippines) of the film remove the John and Judy subplot.
