Austin Butler threw everything into his betrayal of Elvis Presley but still, it comes a shock to learn that the day he completed filming Elvis, the 31-year-old had to be rushed to the emergency room.
Butler told PEOPLE on the red carpet at the SAG Awards Sunday night, "I didn't get sick the entire time I filmed, but the day that I finished, I ended up in the emergency room."
Butler revealed that he spent "a week in bed" before being discharged from the hospital to immediately begin work on another project.
Butler told British GQ, he was rushed to the hospital "due to a virus he contracted that simulated the symptoms of appendicitis."
It wasn't the only injury he suffered regarding Elvis, either.
Butler told PEOPLE that he lost his now-memorable voice while singing Elvis' version of "Never Been to Spain."
"We did so many takes. And at a certain point, I just lost my voice," Butler explained. "So then I went on vocal rest for a couple days, and I was able to come back."
