Based on the novel The Wettest County in the World by Matt Bondurant, and on his grandfather and two great-uncles, the true gangsters story details of the saga of the Bondurant boys, bootlegging siblings who take the law into their own hands in Prohibition-era Virginia while making a run for the American Dream. Nick Cave wrote the screenplay.

Pearce will play an overly violent deputy who comes down hard on the Bondurants while Oldman will play a gangster who engages the boys to deliver alcohol.

Wasikowska (Alice in Wonderland and The Kids Are All Right) plays LeBeouf's love interest, a local Mennonite girl. Clarke (TV's Chicago Code) is playing the brother to LaBeouf and Hardy.

FilmNation Entertainment is handling international sales at Berlin's European Film Market.

The movie is currently in pre-production in Georgia and is scheduled to begin filming on Feb. 28. Lucy Fisher and Douglas Wick will be producing alongside Michael Benaroya under his Benaroya Pictures banner and Megan Ellison.

Jason Blum and Scott Hanson of Blum/Hanson are exec producing along with Red Wagon's Rachel Shane.

Wettest County reteams CAA/Independent Talent Group-repped Pearce with Hillcoat, for whom he starred in 2005's The Proposition.

Oldman, repped by APA and Douglas Management Group, next appears in Warner Bros' Red Riding Hood.
