In the film, Leo plays Alice Ward, the mouthy matriarch of a boxing family. Her performance in this fact-based film has won her one acting accolade after another.
Her next stop is the red carpet at the 83rd Annual Academy Awards.
"I've been told a lot of my life that I should just enjoy things more and I'm so serious and trying so hard to get there. And there is some benefit that comes to you when you enjoy - fascinating," said Leo.
She enjoyed it in 2009 when she walked the carpet for "Frozen River," a film that barely had a budget but sure paid off for Leo.
She's has made several films you'll see this year and has also been busy with her role on the HBO series, "Treme."
While the awards season can be exhausting, it's also exhilarating.
"It could be such a drag, it really could be. There's a lot of travel involved. I flew in yesterday from New Orleans. I was working in my show the day before yesterday. I fly out this afternoon and I work tomorrow again in New Orleans. It could be like, 'wah wah wah.' But it's so much fun," said Leo.
But Leo has also learned how to use her time wisely. These days, she's been known to do her yoga on airlines.
"I'm one hell of an elegant lady," she said.
Leo's calendar is quite full for the rest of the year. She's finished director Kevin Smith's new movie "Red State," which will be out later this year, and has also finished "Seven Days in Utopia" with Robert Duvall. But first... the Oscars!
The Oscars will be presented on Sunday, Feb. 27 at the Kodak Theatre in Hollywood. You can watch the ceremony broadcast live on ABC7 beginning at 5 p.m. PT.
