The Monuments Men has all the hallmarks of a prestige movie: WWII story, a talented actor as the director (Clooney), a great cast. Yet tMM has a fairly uninspired poster.
I can't complain much about the lack of background - it's not a good idea, but it's not fatal, either. This is partly due to the smart color work. Black and yellow are a classic combination and it looks good here, as the colors are not evenly-arranged, but in a way that's pleasing to the eye. And I actually like the tagline.
Also, the lack of creativity - big shots of the major actors involved - is offset because they're presented in a tableau that would remind Americans of the faces on Mount Rushmore.
Unfortunately, Mt. Rushmore has four faces, not seven, so the ad doesn't even properly resemble what it seems to be trying to evoke. It's all a shame, because a movie with this real-life premise (older folks try to save artwork stolen by the Nazi Party) and such solid actors should have a promo that really pops.
