I'm a fan of the films that Adam McKay and Will Ferrell have made together so far. "Anchorman," "Talladega Nights," and "Step Brothers" are all deranged, and they also all have something in common besides the creative teams that made them: I didn't like the trailers at all.
I think what McKay does is context-based comedy. A good example would be that dinner table sequence in "Talladega Nights" where Ricky Bobby (Ferrell) and his wife (Leslie Bibb) and his best friend Cal (John C. Reilly) sit around the dinner table with Ricky Bobby's family, and things break down into a lecture on good parenting and a display of hyperactive hostility and a debate on which Jesus is the right Jesus to pray to. It's a ludicrous, magnificent scene, and it really only works if you see the full thing, start to finish, so you can see how it evolves. There are great lines in the scene ("I"m gonna come at you like a spider monkey!"), but it's the context that really puts it all together.
I say this to preface the release today of the trailer for "The Other Guys," which is the new film that Adam McKay directed, and which stars Mark Wahlberg and Will Ferrell as a pair of mismatched detectives. We've been seeing buddy cop comedies for decades now, as far back as "Freebie and the Bean" and as recently as this spring's "Cop Out." It's certainly not a new idea, but it's one that can provide strong returns in the right hands.
