As for who everyone else is - try and see how many you can identify. It does embiggen on being clicked. This clean version below, from the NYP, gives you an even better look and embiggens even bigger.

If you did a poor job, like me, here's the register (from left to right): Ryan Reynolds, Jake Gyllenhaal, Anne Hathaway, James Franco, Jennifer Lawrence, Anthony Mackie, Olivia Wilde (you may have a harder job spotting her dress), Jesse Eisenberg, Mila Kunis, Robert Duvall, Joseph Gordon-Levitt, Andrew Garfield, Rashida Jones, Garrett Hedlund, and Noomi Rapace.
I love Robert Duvall but slightly mystified at his inclusion amongst this bunch.
Update!
Here is a picture of Jake and Anne, along with a description of the shoot: 'As for the foursome on our front panel, Anne Hathaway (the next Catwoman) was fresh from Oslo, where she had co-hosted the Nobel Peace Prize concert. She was thrilled to see her Love and Other Drugs co-star Jake Gyllenhaal and her Oscar co-host James Franco, who had just completed his finals in a graduate program at the Rhode Island School of Design (he has also taken graduate courses at N.Y.U., Columbia, and Yale). Once Ryan Reynolds arrived from Atlanta, where he was filming The Change-Up, and slipped his superhero physique (his Green Lantern comes out this summer) into a Giorgio Armani tuxedo, the stars were all in place for another classic V.F. tableau.'

And it's hard to go wrong with a picture of Jake and Ryan Reynolds together!

So, to get down to the nitty gritty of what really matters, is this shoot the reason for Jake's shave?
That was the before, here's the after:
