Watch: Brendan Fraser tearfully accepts Oscar for Best Actor

Brendan Fraser left the star-studded audience moved to tears after the actor emotionally accepted his Oscar award as Best Actor for his breakthrough role in The Whale.

Holding the highly-acclaimed statue, The Mummy star was visibly moved with the win and delivered an equally emotional speech as he accepted the prestigious accolade.

"So this is what the multiverse looks like," Fraser said, who returned to the big screen following a break spanning several years.

"My goodness, I thank the Academy for this honor and for our studio A24 for making such a bold film. I'm grateful to [director] Darren Aronofsky for throwing me a creative lifeline and hauling me aboard the good ship The Whale," the actor said.

"It was written by Samuel D. Hunter, who is our lighthouse,” Fraser added before acknowledging his fellow nominees, Austin Butler, Colin Farrell, Paul Mescal and Bill Nigh, for laying “[their] whale-sized hearts bare so that we can see into your souls like no one else could do."

Fraser went on to share that it was an "honour" to be nominated along many other big names and gave special honour to Hong Chau as he said, "Only whales can swim at the depth of the talent of Hong Chau."

"I started in this business 30 years ago, and things, they didn't come easily to me, but there was a facility that I didn't appreciate at the time, until it stopped. And I just want to say thank you for this acknowledgement," Fraser said.

"Because it couldn't be done without my cast. It's been like I've been on a diving expedition to the bottom of the ocean and the air on the line to the surface is on the launch being watched over by some people in my life.

"Like my sons Holden and Leland, and Griffin, I love you Griffey, my manager Joanne Kelowna (spelling?), Jennifer plant. My best first mate Jeannie. Thank you again, each one and all. I'm so grateful to you. Goodnight."
