Family, friendship, and the f’in Catalina Wine Mixer: all will be tested when two middle-aged slackers become Step Brothers in one of most gut-busting, laugh-out-loud comedies of the aughts. When their single parents get married, a pair of reluctant new step-siblings will hilariously go to war but soon discover they have more in common than they thought. And when their immature antics tear the newlyweds apart, they’ll have to find a way to bring everyone back together. Will Ferrell and John C. Reilly star alongside Mary Steenburgen, Richard Jenkins, Adam Scott, and Kathryn Hahn.
