Never heard of it, but it came out in 2011, stars Patrick Dempsey, Ashley Judd, and a whole bunch of those character actors that you'd recognize right away if even you don't always know their names.
Funniest movie I've seen in a long, long time. Takes maybe ten minutes to set up, then things take off and it's easily a laugh a minute from then until the end of the movie. It's one of those flicks you're better off seeing from the beginning so you know what's going on, because it's insane. Not a lot of plot twists, but a few, and mostly it's just crazy, silly fun. No slapstick, just a conflagaration of characters and situations that lead to a lot of really funny lines. The script is perfect, the timing and directing are perfect, the acting and the characters are perfect.
