Star Wars: The Force Awakens celebrated May 4, also known as Star Wars Day and “May the Fourth Be With You,” by revealing the characters played by Lupita Nyong’o, Adam Driver and Gwendoline Christie.

Star Wars: New Photos Of Adam Driver, Gwendoline Christie

To celebrate May 4, Vanity Fair released a sneak peek at exclusive photos from Annie Leibovitz, to be published in the June issue of the magazine. The photos include previously seen new characters, including John Boyega’s Finn and Daisy Ridley’s Rey who appear on the cover alongside Peter Mayhew’s Chewbacca and Harrison Ford’s Han Solo.

Not featured on the cover are fellow newcomers Driver, Nyong’o and Christie. All three actors have so far remained out of the Star Wars: The Force Awakens spotlight, with very little information about their characters released up to this point. New photos, however, confirm that Driver is, indeed, playing the new baddie Kylo Ren. In the photo released by Vanity Fair, Driver “commands snowtroopers loyal to the evil First Order on the frozen plains of their secret base.”

The photo of Nyong’o is much less telling. The Oscar winner will be playing a CGI character in the film, and appears to have done at least a majority of her performance as Maz Kanata in motion capture. As Kanata, Nyong’o will appear in the film as a pirate with no allegiances.

Last but not least, Christie, who took to Twitter to celebrate May 4, appeared in a portrait shot by Leibovitz. Christie stands tall, covered in armor and a helmet, as Captain Phasma, a member of the First Order (presumably following the rule of Driver’s Kylo Ren.)
