Video: Watch Hannah Waddingham Talk Olivier Awards Opening on THE TONIGHT SHOW WITH JIMMY FALLON

Hannah Waddingham stopped by The Tonight Show with Jimmy Fallon on Monday evening to discuss her role in the film The Fall Guy and other projects.

To kick off the conversation, Fallon complimented her on hosting the Olivier Awards in April, particularly praising the opening number where the actress performed Anything Goes.

"I kind of picked a fight about the opening," she told Fallon.

After receiving the music, she worked with her pianist Joe Stillgoe to add some new lyrics to the Cole Porter classic in an effort to "set the tone for the whole night to not be stuffy."

"I put my hands on the music and went 'Right.' And he went, 'Oh, God.' He said it was literally like I pulled a pin out and chucked a grenade in 10 days before."

"I picked a fight and it was worth it," she concluded.
