The force was strong with Prince William and Prince Harry as they attended the UK premiere of Star Wars: The Last Jedi in London.

The brothers turned heads on the red carpet, posing with Stormtroopers and droid BB-8.

Their red carpet appearance is not the only part they played in the movie, as the princes have also reportedly had cameo appearances as Stormtroopers.

The royals are believed to have filmed the scenes during a "private tour of Pinewood Studios in Buckinghamshire last year", the UK's Telegraph reports.

"I actually felt more nervous because I didn't know what I was doing the first time around, and you kind of think, how am I supposed to do something again when I didn't know what I did the first time?" Ridley said, according to the Daily Mail.

"And I think because people responded so well to [co-star] John [Boyega] and I together that was a big thing too, thinking how are people going to respond when we're not together. So it was nerve-racking," she added.

"But again, as relationships grow and you start to get comfortable, it settles into a wonderful six months."

Fresh from his engagement to Meghan Markle, Prince Harry was accompanied by his brother Prince William to the premiere, also attended by Star Wars favourites C3PO and R2D2.
