The script by Mike Arnold and Chris Poole prompted a bidding battle two years ago, before New Line got it as part of a two-picture deal. McConaughey will play a barroom fighter in New Orleans who hires himself out for $250 to settle disputes for people who can't afford to hire a lawyer. Harsh language and quick fists are his weapons of choice.

The project will aim for an R rating and fits more closely in the mode of "Wedding Crashers" than some of the romantic comedies and adventures in which McConaughey has starred recently.
