Daniel Radcliffe recently sat down with Jimmy Fallon and the two started discussing how hard it is to do accents. Americans have a tough time doing a real British accent, often going either “very posh,” as Radcliffe says, or Cockney.

But Brits tend to aim for a stereotypical deep drawl, almost Texan, and hope to land somewhere in the middle as sounding average American.

Radcliffe admitted that he learned a lot about speaking with an American accent from watching professional wrestling on television. In fact, when playing with his WWE action figures as a child, he would have them speak with the appropriate American accents.

“The Rock was always my favorite,” he told Fallon. “I harbor a not-so-secret desire to somehow find parts for me and Dwayne Johnson to play in the same movie. He knows I’m a fan… We have mutual friends. I actually have a t-shirt of him holding up a sign that says, ‘Dan Radcliffe, Number One Fan.’”

Fallon pressed on about the idea of a film collaboration between Johnson and Radcliffe.

“My initial thought was like a buddy cop movie,” Radcliffe told him, “with two unlikely partners who are forced to work together.”

Radcliffe then started to riff on possible names for such a film, including puns about two cops who love music called “Siren Song”.

Dwayne Johnson, whom Fallon was quick to point out watches the show, tweeted out his own film name idea.
