Professional jackass Johnny Knoxville and Patton Oswalt, widely regarded as one of the best and most transgressive stand-up comedians of the last decade, have signed on to co-star in The Catechism Cataclysm director Todd Rohal's latest film, an outlandish yet poignant comedy about a pair of battling brothers who attempt to honor the memory of their ailing father by taking a troop of boys on a camping trip that goes wildly wrong.

The still untitled film from emerging comedic auteur Rohal is loosely based on his experiences growing up. Production began several weeks ago, during the last week of August, and Maura Tierney, The Daily Show correspondent Rob Riggle, and Patrice O'Neal are also on board for the ensemble comedy. Look for more on The Catechism Cataclysm, meanwhile, next week.
