This final poster for Hairspray travels some of the same paths that the earlier posters travelled. Colorful! Fun! Fifties! Music! Star filled ensemble! And it does a good job of packing all that in. But with a musical, more than with any other kind of film, the trailer is the one that is going to have to do the majority of the selling. The poster does I nice job of reminding us of the film, but it won’t really make anybody interested on the film by itself.
