Creepy, a little sinister and perfectly capturing the overall feeling of Fritz Lang's masterpiece. There are many different versions of the Metropolis poster, but this one is my absolute favourite.
I particularly love the way that the canons are pointing directly at the viewer. Sergei Eisenstein's film can't really be accused of subtlety (subtlety would in fact undercut its point) and neither can the poster with its "with us or against us" attitude.
Where to begin? I love the way that the poster captures the dynamic between the protagonist and his love interest. The way he's blocking her path with his leg suggests the sense of entitlement he has as a rich American, but the look on his face also makes it clear that he's in love with her. It's also perfect that he's sort of half-in and half-out the door since the two will soon be separated by WWI.
The artwork for this poster is really gorgeous, so it's a great poster simply from an "oooh, pretty" standpoint. It also handily evokes the sense of fun and adventure inherent in the story.
Back in the day, Rudolph Valentino was the guy and this poster for his biggest hit captures the raw, slightly dangerous, sexuality he possessed which drove women nuts. Yes, it's kind of problematic racially and from a feminst stand point, but it's from 1926. What wasn't racist and sexist back then?
