Austin Butler? Great choice. I wrote about the film Elvis on CineTV last year - https://peakd.com/hive-121744/@thunderjack/review-elvis-2022
Although it is the only film Butler has been in that I have seen, I have to say that not only did he turn in an incredible performance, he also proved to be a credible Elvis. I think he is going to have a very good and very long career in film.
