Why is this monkey wearing a Rolling Stones jacket, and whose arm is that?  You'll have to click the story to see the full image from 'The Hangover Part II'

The Internet has changed the way movie information is shared with fans, and in ways that personalize the process in ways I'm guessing no one could have ever predicted.

Earlier tonight, Todd Phillips, the director of "The Hangover" and "Old School," posted a new picture to his Facebook account.  It's a shot of the returning cast from the original "Hangover," along with a monkey in a Rolling Stones jacket.

It's not a groundbreaking earth-shattering moment in movie publicity, sure, but the casual way Phillips tossed it up on the Facebook account and then started conversing with people as they posted reactions to it is sort of amazing.  When I was a kid, growing up a million miles away from any sort of movie production, I would have loved to have had a way to talk directly to filmmakers, especially while they were in the middle of making a film.  Now, that's possible.

My favorite touch about the photo is the tattoo on Ed Helms's face, which seems to be the exact same tattoo that Mike Tyson has on his face.  I'm really weirded out by the bald Zack Galifianakis, and I'm guessing there's a backstory on why he has no hair this time.

As Phillips pointed out, getting legal clearance on that jacket that the monkey is wearing was not an easy thing.  The Rolling Stones are very, very picky about letting people use that logo, and Phillips had to get them to personally agree.  Seems like they must have been fans of the first film, though, and so… whatever it is that's happening in the photo is… happening...

So without further adieu, I ask you, "What the hell is going on here?"

"The Hangover Part II" arrives in theaters .
