Horrible Bosses (2011)

A dark comedy where Nick, Dale and Kurt are three friends who share a common feeling: they are fed up with their bosses. With the assistance of an ex-convict, they come up with a crazy plan to murder them, but things don't turn out as expected and everything leads to crazy and tragicomic situations. The film is extremely funny and irreverent thanks to the acting duel between the leading trio (Jason Bateman, Charlie Day and Jason Sudeikis) and the tyrannical bosses (Colin Farrell, Jennifer Aniston and Kevin Spacey).
