Funnyman Jim Carrey is in talks to star in Loomis Fargo, an action-comedy flick based on real-life events centering on an armored car heist.  The pic revolves around four dull-witted Southerners who managed to rob a Loomis Fargo armored car to the tune of $17 million.  Jared Hess (Napoleon Dynamite) will direct from a script in turns by Emily Spivey, then Danny McBride and Jody Hill, and finally Chris Bowman and Hubbel Palmer. Hit the jump for more on this project, including details on Carrey's potential character. Variety reports that Carrey is in talks to star as Dave Ghant, a military vet and Loomis Fargo night guard who acts as the gang's ringleader.  Relativity Media is in the process of acquiring rights to the picture, with Lorne Michaels and John Goldwyn producing.  In addition to Napoleon Dynamite, Hess has also directed Nacho Libre and Gentlemen Broncos.  If you're a fan of (or at least familiar with) those films, you can take a good guess at the type of humor you should be expecting.  Production on Loomis Fargo aims to start in North Carolina this coming April.Carrey is currently filming director Jeff Wadlow's Kick-Ass sequel as Colonel Stars, a founding member of the vigilante team, Justice Forever, who recruits other would-be superheroes.  The picture reunites original stars Aaron Johnson, Christopher Mintz-Plasse, Nicolas Cage and Chloe Moretz.  Newcomers Donald Faison, John Leguizamo, Lindy Booth and Olga Kurkulina also star.  Carrey will next be seen opposite Steve Carell and Steve Buscemi in the Don Scardino-directed magician comedy, The Incredible Burt Wonderstone.  The picture also stars Olivia Wilde.
