The trailer for Step Brothers — starring Will Ferrell and John C. Reilly, and releasing July 25 from Sony — is online, and it totally works as a territorial pissing match/slice of locked-horn competitiveness between two oblivious man-children. A reunion of sorts between Ferrell and Talladega Nights co-writer-director Adam McKay — who also teamed up for the smash web short “The Landlord,” which was probably seen by more folks than saw Semi-Pro — the movie centers on two oafish fortysomethings who live at home with their respective parents (Richard Jenkins and Mary Steenburgen) who are then forced to coexist when their folks get married.

It’s good that that the movie seemingly pivots from being a thing of straight-up competition into, however ramshackle and loosely formed, an exercise in shared doofishness. Reilly and Ferrell both exude a certain affability, and their carefully constructed relationship was a good part of Talladega Night‘s success. Though the trailer is noncommittal in this regard, the studio-peddled logline seems to indicate the film is basically a re-do, on some level, of The Parent Trap, which could be great. The trailer also has the good sense to end with a great visual gag.
