After playing a disgruntled employee who hires an assassin in the New Line comedy Horrible Bosses, Jason Sudeikis has signed on to play a hitman himself in Relativity Media's Untitled Heist Comedy, which was formerly known as Loomis Fargo.

Owen Wilson, Zach Galifianakis and Kristen Wiig are attached to star in the comedy, based on the true story of four Southerners who managed to pull off a $20 million heist. Zach Galifianakis stars as a disgruntled armored truck driver, who teams up with his workplace crush (Kristen Wiig) and her crew to rob the bank's vault. After they double-cross the driver in Mexico, he becomes hell-bent on getting his revenge. No further details were given for Jason Sudeikis' hitman character.
