What’s more, Ferrell and McKay continue to write together, so even if there’s never a sequel, the possibility of the next Step Brothers, the next incredibly funny, and totally original idea, is also a strong possibility.
While this makes it seem like a Step Brothers sequel is the last thing we’ll ever see, folks shouldn’t give up on the concept entirely.
Director Adam McKay says that the central joke of the film only gets funnier the older that Will Ferrell and John C. Reilly become, so the possibility of going back to it at some point down the road will always be there.
