EXCLUSIVE: The impressive volume of distribution deals for 2011 Sundance Film Festival fare is about to expand again. I’m told that ATO Pictures is wrapping up a deal for US rights to The Convincer, the Karen Sprecher-directed dark comedy that stars Greg Kinnear, Alan Arkin and Billy Crudup. It’s Fargo-style caper-gone-awry tale in which a conniving insurance salesman (Kinnear) thinks he has found a way to fortify his bank account and get his wife back. He sets out to scam a retired farmer (Arkin) out of a rare violin worth $25,000. A lot goes wrong and blood and dead bodies ensue. Produced by Werc Werk Works, the film was scripted by the director and her sister Jill, who also did Clockwatchers together. CAA is repping the film.  ATO, which was hatched by Johnathan Dorfman, Temple Fennell and musician Dave Matthews, distributed George Hickenlooper’s final film Casino Jack and recently acquired The Woman in the Fifth.
