Brother&#39s Justice

Comedic actor Dax Shepard wants to change genres: with friend and producer Nate Tuck, he concocts a concept for an action film featuring martial arts. They drop in on Ashton Kutcher to see if he&#39ll co-star, ask Jon Favreau to direct, and seek advice from Tom Arnold (because he was in "True Lies"). The road to a green light is rough, full of stops and cul-de-sacs. Along the way there&#39s a front-yard wrestling match with Bradley Cooper and David Koechner, back stories on other Shepard/Tuck ventures, and a rupture in a life-long friendship. Can Dax get his kung-fu movie made in spite of rejection?
