There's probably never been a better case to be made for red-band, unrated trailers than in this one for Walk Hard: The Dewey Cox Story. Until this, I had complete disinterest in watching John C. Reilly pretend to be Will Ferrell as he sings through a series of cock jokes. But throw in a shot of him cutting his young brother in half with a machete and yelling "f*** you" at a chimp and this is suddenly looking like a much better movie.
So maybe it's actually less a case for red-band trailers, more support for the destruction of children and chimps.
Thanks for the tip, Kyle. Trailer under the cut.
