Movie Posters Grouped by Theme

I recently came across a clever French blog (no, not Le BuboBlog, which has no affiliation with this one). It's a site that groups together movie posters by theme; say, ones that feature a park bench or people wearing sunglasses.

You often hear talk about how formulaic movie trailers are (epitomized by this generic film preview). This French guy's site really demonstrates how formulaic posters are as well.

So what appeals to filmgoers?

Apparently they like to see movies about people with text over their blindfolds...

...or dark figures with their backs to the audience...

...or close-ups of eyeballs...

...or women in red dresses.

You can see many more examples here. (And thanks for the tip, BuboBlog Portola Valley correspondent Jon.)
