Rainn Wilson says he wasn't happy while filming 'The Office' because 'it wasn't enough'

• Rainn Wilson, an Emmy-nominated actor, opened up about feeling unfulfilled.
• Wilson, known for his role in "The Office" as Dwight Schrute, said he was sometimes unhappy on the show.

Actor Rainn Wilson opened up about feeling unfulfilled while filming some seasons of the hit show "The Office," in which he played the chaotic character Dwight Schrute.

As he promotes his newly released book, "Soul Boom: Why We Need a Spiritual Revolution," Wilson has been frank about some of the highlights of his career, specifically in how the grass always looks greener elsewhere.

"When I was in 'The Office,' I spent several years really mostly unhappy because it wasn't enough," Wilson said on Bill Maher's "Club Random" podcast. "I was making hundreds of thousands. I wanted millions, and I was a TV star, but I wanted to be a movie star. It was never enough."

The podcast episode has not yet been released, but a transcript was provided to OutKick, which first reported on the interview.

Wilson reflected that he was working with A-list actors but still felt unfulfilled, even when the show was incredibly successful. To combat that, he took "a really deep dive into spirituality," which is the topic of his latest book, according to TODAY.

"I'm on a hit show, Emmy nominated every year, making lots of money working with, like, Steve Carell and Jenna Fisher and John Krasinski and these amazing writers and incredible directors like Paul Feig," he said. "I'm on one of the great TV shows. People love it. I wasn't enjoying it."

"I was thinking about, 'Why am I not a movie star? Why am I not the next Jack Black or the next Will Ferrell?" he added. "How come I can't have a movie career? Why don't I have this development deal?'"

The actor also said he only signed on for the hit show in order to buy a house, but he acknowledges he became a part of something much bigger.

"I wasn't thinking about giving laughter as a therapeutic remedy and a balm and a salve to a hurting populace," Wilson said on the podcast, per OutKick. "What an honor it was to be a part of something like that."
