I don't know much about Austin Butler's work, although I read somewhere that he participated in Tarantino's Once Upon a Time in Hollywood, which I must revisit to locate this actor's performance. However, I have seen Baz Luhrmann's film about Elvis Presley.
Butler gives an electrifying performance as Elvis, he manages to transmute and become Elvis himself, it is one of the best performances, in my opinion, of the year 2022 even far superior to that of Rami Malek in Bohemian Rhapsody.
He won the Golden Globe award for best actor in a drama film, I don't know if his performance was better than Brendan Fraser's in The Whale because even in my country Venezuela Fraser's film is not available.
The last public appearance I saw of Butler was next to the late Lisa Marie Presley, (Elvis Presley's daughter), at the Golden Globe Awards on television.
