A political comedy starring Will Ferrell, Zach Galifianakis, John Lithgow and Dan Aykroyd - you can't go too wrong with that lineup really (and we don't need to tell you why it's a pretty appropriate time to watch this movie). Ferrell plays a long-serving congressman who finds himself up to his neck in yet another scandal, leading two corrupt businessmen to believe they can easily take him down and put in a candidate they could control. Roll up Galifianakis, as the naive do-gooder that will run against him. And sure you don't need us to tell you that this pair on screen together is just guaranteed laughs really.
