Long before he became an Oscar-nominated Hollywood A-lister, Bradley Cooper was paying his dues with a number of comedic supporting roles. One of the first to get him noticed was as Rachel McAdams' conniving, mean-spirited boyfriend Sack Lodge. Cooper's driving force in this movie is to marry into McAdams' family and there's no better way to propose than by blindsiding your girl with a surprise wedding announcement at a family gathering. Fortunately, McAdams comes to her senses after a movie's worth of mistreatment to throw this loser aside.
