A short (and I'm sure flawed) observation I just made with regard to posters for action movies. Paramount have released their new character posters for the upcoming G.I. Joe: The Rise Of Cobra and I couldn't help but notice similarities to the promotion of Watchmen and its character posters...

Most notably, I noticed the stark contrast in their poses - the token female characters tend to have the emphasis on their posteriors. I thus noticed that in action movie posters, men generally never pose with their backs to camera.

Not really a spectacular epiphany I know. But it's mine.

Now you observe the butts and chests of the Watchmen and the G.I. Joe team.
