Brendan Fraser gatecrashes cinema’s screening of The Mummy dressed as Rick O’Connell

Brendan Fraser has left cinema goers absolutely stunned after gatecrashing a screening of The Mummy.

The Prince Charles Theatre in London decided to put on a back-to-back showing of the incredible 1999 film and its sequel The Mummy Returns.

It was a full house as people crammed into their seats to watch the double up on 35mm film.

While everyone thought it was a treat unto itself that they could see two epic movies, they couldn't believe their eyes when the star of the show appeared from nowhere.

People leapt to their feet in applause and cheer when the actor, who was dressed as Rick O'Connell (Fraser's character in The Mummy movies) made his way to the stage.

After a lengthy standing ovation, the 54-year-old thanked everyone for their warming welcome.

"I am proud to stand before you tonight," he told the crowd.

"Friday night in Leicester Square...I first started seeing films right across the street, I saw Star Wars in 1977 and it changed my life, made me want to star in movies.

"And this is a film that was made in Britain, you should know that. Shepperton I believe.

"We shot it in Morocco, and even the second one too, be proud. Thank you for being here."

He reflected on the wild ride that The Mummy was when they shot it back in the late '90s.

"We had no idea what kind of movie we were making when we shot this," he said.

"We didn't know if it was a drama, a comedy, a horror movie, straight action, all of the above.

"No idea, until it tested in front of British audiences, thank you for that."

He ended his speech by encouraging people to see his new movie, The Whale, which has been absolutely praised by critics so far.

His performance has earned him a nomination for Best Actor at the Golden Globes (which he lost to Austin Butler for Elvis), the Critics Choice Awards (which he won), and now the Academy Awards.

It's his first ever Oscar nomination and fans believe his portrayal of Charlie is the best performance of his career.

Charlie's weight gain is a result of a spiral of guilt-induced binge eating after having left his family for a gay lover who later died.
