You probably think that the only reason why we’d be posting the 27 Dresses trailer is because of Katherine Heigl. And you would be right in your assumptions. It’s a romantic comedy about marriage, so what more can I say? They are promoting it as “From the screenwriter of The Devil Wears Prada and starring “Knonked Up‘s Katherine Heigl”. It’s so funny how studios decide to market movies now-a-days. I’m not saying they are wrong, it’s just very amusing. Check out the trailer after the jump.
