So, here is the deal: you either find the idea of Patrick Dempsey as a maid of honor hilarious or you don’t. No poster is going to make you want to see this movie if that basic premise doesn’t appeal to you. At least no poster that is at all honest about the film’s content.
Considering that constraint I think the poster does a fine job of selling the movie. The film’s concept is conveyed quite clearly, Dempsey looks good stands out nicely in the poster, and we even get a little bit of Michelle Monaghan, which is always nice. I’m not sure how wise it is to center a marketing campaign on Dempsey, considering he is unproven (to say the least) as a movie star. But again, that goes to the movie, and the marketing team can’t do much to get away from it.
