Step Brothers (2008)

Brennan Huff and Dale Doback are both about 40 when Brennan's mom and Dale's dad marry. The sons still live with the parents so they must now share a room. Initial antipathy threatens the household's peace and the parents' relationship. Dad lays down the law: both slackers have a month to find a job. Out of the job search and their love of music comes a pact that leads to friendship but more domestic disarray compounded by the boys' sleepwalking. Hovering nearby are Brennan's successful brother and his lonely wife: the brother wants to help sell his step-father's house, the wife wants Dale's attention, and the newlyweds want to retire and sail the seven seas. Can harmony come from the discord?—
