John Boyega Reveals Who Was Cooler Between Prince William, Prince Harry On 'Star Wars' Set

John Boyega has shared who he thought was cooler between Prince William and Prince Harry during their visit to the set of "Star Wars: The Last Jedi."

The royal brothers visited the set of the movie in 2016 and reportedly even filmed a cameo as Stormtroopers, which didn't make it to the big screen.

During an appearance on Thursday's episode of "Watch What Happens Live With Andy Cohen," Boyega — who played stormtrooper-turned-hero Finn in the "Star Wars" sequel trilogy, spanning from "The Force Awakens" in 2015 to "The Rise of Skywalker" in 2019 — was asked by fans who was cooler on the set between the two royals.

"I definitely think it was Harry. Harry is just more casual, isn't he?" the 30-year-old "Woman King" star responded.

Boyega also shared his theory on why Prince William and Prince Harry's cameo was ultimately cut from the final film.

"I don't know why. Maybe the royal family were like, 'Nah, leave them out of the 'Star Wars' universe,'" the actor said, before joking, "There's something about royalty. It just seeps through the suit. No, I'm sure that they had their reasons."

The Golden Globe winner also revealed that the royals weren't the only high-profile stars who visited the set that day.

"[William and Harry] walked on with the big costumes on. They got in the elevator because it was a big elevator scene," Boyega shared. "Tom Hardy was on set that day, so it was kind of random. 'Star Wars' is open for everybody. You want to do a cameo? Just show up. It's like a block party."

In April 2016, the royal siblings were given a behind-the-scenes tour of Pinewood Studios in London, where they met Boyega, Mark Hamill, Daisy Ridley and director Rian Johnson on the set of "Star Wars: Episode VIII."

Prince Harry was able to sit in the cockpit of an A-wing fighter, while Prince William was introduced to BB-8 during their visit. The pair also received hugs from Chewbacca and had a lightsaber fight with each other.

The trip came years before the Duke of Cornwall and the Duke of Sussex's reported rift. They became estranged after Prince Harry and his wife Meghan Markle stepped back from royal duties and moved to California in 2020.

Ahead of the release of her new royal book, "The New Royals — Queen Elizabeth's Legacy and the Future of the Crown," Vanity Fair's royal correspondent Katie Nicholl claimed on "Dan Wootton Tonight" that Prince William "simply can't forgive" his younger brother.

"He always thought Harry would be his wingman, now he's doing it on his own. Thank goodness he's got Kate by his side," Nicholl claimed.

The brothers reunited earlier this month after their grandmother, Queen Elizabeth II, passed away at the age of 96 on Sept. 8. Prince William and Prince Harry, along with their respective wives, put on a united front during a royal walkabout to greet mourners outside Windsor Castle on Sept. 8 and attended the Queen's funeral in London on Sept. 19.

Prince Harry and Markle have since returned to California.
