Step Brothers takes two grown men who still live at home and forces them to become siblings overnight, then watches the sparks fly.

What is Step Brothers about?

Brennan Huff has spent his adult years living comfortably with his mother, and Dale Doback has done much the same with his father, both content to avoid anything resembling responsibility. Everything changes when their single parents fall in love and marry, suddenly turning two lifelong strangers into stepbrothers sharing one house. What starts as open hostility between them, complete with petty sabotage and territorial disputes, slowly bends toward an unlikely friendship, even as their parents' new marriage buckles under the strain of housing two overgrown children at once.

About the cast

Will Ferrell plays Brennan and John C. Reilly plays Dale, the two man-children whose rivalry and eventual bond carry the film. Mary Steenburgen and Richard Jenkins play their respective parents, watching their new marriage get tested by their sons' antics, while Adam Scott appears as Brennan's more conventionally successful younger brother. Kathryn Hahn plays that brother's wife, adding another layer of tension whenever the extended family gets together.

Context & significance

Adam McKay directed and co-wrote Step Brothers, working again with Will Ferrell after a run of broad studio comedies built around Ferrell's willingness to play characters with almost no self-awareness. The film leans on that same comic instinct, pairing Ferrell with John C. Reilly in a chemistry the two had already tested in supporting roles for McKay. Rather than following a tightly plotted story, the film builds its comedy out of escalating set pieces between the two title characters.
