McKay co-writes (with Ferrell) and directs this comedy about two middle-aged men who become roommates when their parents get married. Ferrell stars as Brennan Huff, while Reilly appears as Dale Doback. Ferrell explains his approach to his character:
Well, it’s not far from my current status. I just tried remembering back to those feelings when you felt awkward and shy in adolescence. One of those things about being an actor is that we don’t have to fully grow up in a way.
The film is made with an estimated budget of $65,000 and makes $30,940,732 in its opening weekend.
