Austin Butler

Austin Butler appeared on "The Tonight Show" and showed off his "Elvis" impressions to Jimmy Fallon.

Austin Butler responds to claims that his voice changed after playing 'Elvis' in Baz Luhrmann's new movie.

While Butler's everyday voice may now have a tinge of Presley, it's not at all the same as going full Elvis—which he demonstrated while a guest on The Tonight Show With Jimmy Fallon on June 15. Still, there is a distinct tonal difference between how Butler spoke before he was cast as Elvis Presley and how he speaks now, after imitating the King's idiosyncratic baritone every day for so long. “Certain situations trigger it, I think,” he said with a smile, like being surrounded by Elvis's name at all times.

Austin Butler, who plays Elvis Presley in an upcoming biopic directed by Baz Luhrmann, taught Jimmy Fallon some of the late singer's iconic moves.

“It was all the music moving him.” “He’s the best.” I know that I’m constantly changing.”

On "The Tonight Show starring Jimmy Fallon," Austin Butler recalled meeting Priscilla Presley after being cast as Elvis Presley in Baz Luhrmann's film ...

"I went over there for the first time, and I spent the whole day in there by myself," he added. "Then she gave me this big hug and she said, 'You have a lot of support.' And that was huge," the actor said. It was so amazing."

Austin Butler has more than singing and dancing in common with Elvis Presley.

“When I learned about his mom — and then knowing that we were the exact same age — that just hit me,” he said. The biopic chronicles Elvis' rise to fame while maintaining a complicated relationship with his manager, Colonel Tom Parker. While on TODAY with Hoda and Jenna Thursday, Butler —who plays the late legend in the upcoming biopic, “Elvis" — said he initially struggled with tapping into Elvis' character beyond surface-level elements.

Audiences around the world will finally get to see Butler's mind-blowing performance in "Elvis" on June 24. Austin Butler is still very much tapped into his Elvis Presley portrayal. The "Elvis" star — still partially using his Elvis accent — called the film "the biggest responsibility I've ever felt," revealing that he leaned into his role as much as he could to bring an authentic depiction of the late singer to life.
