Princes William and Harry could be in the upcoming Star Wars blockbuster after a secret filming session at Pinewood Studios, it has been revealed.

The pair are believed to have filmed cameo roles as Stormtroopers alongside Daisy Ridley, John Boyega and Benicio del Toro when they visited the set last week.

The Duke of Cambridge and his brother were pictured being hide their excitement as they met Luke Skywalker himself, actor Mark Hamill, and Harry had a bear-hug from Chewbacca.

But after being shown around the studio the stage was cleared – leaving the two princes, the director, producer and essential crew members to secretly film the scene that could feature in the eighth Star Wars blockbuster, the as yet unnamed Episode VIII.

A source told The Mail on Sunday: "The line given was that they were going to have lunch and a private tour of the rest of the set.

"What really happened is that the director came over and told them it was time to “get suited” and off they went to the wardrobe department.

"The Princes dressed up in full Stormtrooper gear and filmed a scene in which Rey and Finn infiltrate a secret base. The rebel characters are in a lift with Benicia del Toro’s character when a group of Stormtroopers enter – two of whom are William and Harry."
