Like Transformers, I'm pretty sure Hairspray is all set when it comes to the heavy promotion, and some of the clips from the movie I've seen online recently are not particularly noteworthy.
This one, however, made me laugh and gave me the creeps all at the same time. There's just something about photographs coming alive and singing that leaves me not quite knowing what to say. You couldn't do that with a stage musical.
There's no Travolta-in-drag-and-prosthetics, but it's a clip worth watching regardless, so
