Austin Butler put his all into playing Elvis Presley in Baz Luhrmann’s upcoming biopic.

The former Nickelodeon and Disney star chats to British GQ about taking on such a role, admitting his body shut down the day after wrapping the project in March 2021.

Butler was diagnosed with a virus that simulates appendicitis and spent a week bedridden: “I woke up at four in the morning with excruciating pain, and I was rushed to hospital. My body just started shutting down the day after I finished ‘Elvis’.”

He adds of losing himself in becoming Elvis: “You can lose touch with who you actually are. And I definitely had that when I finished ‘Elvis’ – not knowing who I was.”

Butler, who stars in the flick alongside Tom Hanks, Olivia DeJonge, and Dacre Montgomery, shares of how he felt meeting Priscilla Presley: “She looked like an angel, I walked down the hall with Baz afterwards with tears in my eyes.”

He admits that he and Elvis had things in common on a personal level, telling the magazine: “His mother passed away when he was 23, and my mum passed away when I was 23, so when I learned that, it was one of those things where I got chills, and I just thought, Okay, I can connect to that.”
