It turns out that Tom Hardy has a secret obsession.

Tom Hardy Gets Compared To Iconic Movie Star

According to Friday's report from Us Weekly, the Oscar nominee likes to take time on his own away from his wife and child to go to the theater- specifically to watch ballet.

"Tom loves to sneak off by himself to the English National Ballet to unwind," a source told the site. "He'll throw on a cap so no once notices him."

This seems to be one of the actor's happy places where he'll sometimes bring a family member with him.

"He'll sit in the audience just before the show starts," the source said. "Sometimes he's brought his mom!"

Some of Hardy's previous credits include Mad Max: Fury Road, Inception and The Dark Knight Rises. He was nominated for an Academy Award this year for his role in The Revenant.

The actor's popularity has gained so much praise that even iconic movie star Jane Fonda compared him to legendary actor Marlon Brando.

"I saw The Revenant and asked who played the bad guy," Fonda said in a report from USA Today. "It was Tom Hardy and then a lot of folks said, 'You gotta see him in Legend. There he played twin brothers who are British gangsters. He is really amazing in this film. I came to think of the two brothers and different people even though Hardy was playing both. And, as the more together of the brothers, Hardy is like a new Brando."
