 There are subtle differences between the same scenes in the USA and UK  versions of the movie.  This includes not only different takes of the scene,  but sometimes different dialogue.  For example, one  version of the first job  interview has a question about "the El Niño phenomenon", others have a  question about Microsoft.  In addition, during the credits, the USA version  has a home movie of Mark Darcys 8th birthday party with the young Bridget.   The UK version has interviews with the various characters about the new  relationship between Bridget and Mark.
