Warning: Potential spoilers follow for "Star Wars: The Force Awakens"

New images have leaked for "Star Wars: The Force Awakens" revealing appearances by two characters from "Return of the Jedi" and scenes from the J.J. Abrams movie itself.

All of them come from the fan site Making Star Wars, which has three promotional images depicting Admiral Ackbar, Nien Nunb, and longtime Abrams friend and collaborator Greg Grunberg wearing an X-Wing pilot's costume. (We've heard the Ewok rumor, but who would've guessed Ackbar and Nien Nunb?)

The site has also posted movie screen grabs that show Harrison Ford's Han Solo, Daisey Ridley's Rey and John Boyega's Finn in the cockpit of the Millennium Falcon, and Domhall Gleeson's "General" with Gwendoline Christie's Captain Phasma.

"Star Wars: The Force Awakens" opens Dec. 18.

Update (11:39 a.m.): We've removed the images at the request of Disney.
