The first photos have emerged of January Jones as Emma Frost on the Pinewood Studios set of X-Men: First Class, Matthew Vaughn's swinging '60s reboot of the Fox franchise. (Yes, I know that some insist it's a prequel, but I don't buy it.) You can go here and here to see more images on Jones in her all-white ensemble.

First Class, which began filming last week in England, centers on the early friendship between Charles Xavier and Erik Lensherr, who work with other mutants to stop a global threat. In the process, a rift between them opens, beginning the war between Magneto’s Brotherhood and Professor X’s X-Men. It's set for release on June 3, 2011.

The film so far stars: James McAvoy as Charles Xavier; Michael Fassbender as Erik Lensherr; Kevin Bacon as Sebastian Shaw; January Jones as Emma Frost; Jennifer Lawrence as Mystique; Nicholas Hoult as Henry McCoy/Beast; Caleb Landry Jones as Sean Cassidy/Banshee; Lucas Till as Alex Summers; Edi Gathegi as Darwin; Jason Flemyng as Azazel; Rose Byrne as Moira MacTaggart; Zoe Kravitz as Angel Salvadore; Bill Milner as young Erik Lensherr; and Morgan Lily as young Raven Darkholme/Mystique.
