Austin Butler and Denzel Washington

Austin Butlerholds enormous respect forDenzel Washington, an actor theElvisstar considers “the godfather of acting.”

In a new feature interview withBackstagemagazine published Wednesday, Butler, 31, said that working with Washington, 68, on the 2018 Broadway production of Eugene O’Neill’sThe Iceman Cometh"changed my perception of myself and my abilities."

“Something Denzel told me is: There is no stage acting or film acting; there is the truth,” Butler told the outlet, which noted theElvisstar “frequently returns” to lessons he learned while working with Washington.

“Human beings do really broad things in everyday life,” Butler continued in the interview as he spoke of the veteran actor’s advice. “Sometimes, they do very subtle things. You can do either onstage or onscreen.”

“That freed me up to realize [that] all of the things I was learning onstage—I could take them back into film,” he added of the experience.

Elsewhere in the interview, Butler recalled how he doubted he would even land his role inThe Iceman Comethin the first place.

“I did not know Denzel,” Luhrmann clarified of the call to the outlet. “And he said, ‘I’ve just worked with this guy on stage. I’ve never seen a work ethic like it.’ "

Luhrmann also recalled the conversation with Washington in a panel conversation about the movie withSiriusXMin June 2022.

" ‘You’re about to meet an actor I’ve been on stage with,’ " the director recalled of Washington’s pitch for Butler at the time. " ‘You will not believe this young man’s work ethic, there is just no minute he won’t give to the art.’ "
