Usually to find great poster art you have to go to Mondo or something. Modern posters are full of big heads and famous starts without much striking about them at all. They’ve all been co-opted by PR firms who have done so many studies they know exactly what works.
Then there’s this new poster for the upcoming Godzilla. If the movie is half as dramatic as this poster is it’s going to be amazing. I’d say more, but it kind of speaks for itself.
