The 41-year-old actor revealed as much in an interview with the Huffington Post on Wednesday. Harris hosted the Academy Awards for the first time in February, and told the website he found the job too demanding to do again.
"I don't know that my family nor my soul could take it," he joked. "It's a beast. It was fun to check off the list, but for the amount of time spent and the understandable opinionated response, I don't know that it's a delightful balance to do every year or even again."
