During a call in interview on Australian radio show Fitzy and Wippa, the 51-year-old dished on his weight loss journey, revealing that he's shed 52 pounds since beefing up for his role opposite Ryan Gosling.
"I was 121.6 kilos (268 pounds) the first week of August last year," he said. "I did a movie called The Nice Guys, so I wanted to be the physical juxtaposition of Ryan Gosling."
Sharing that he's already at about 98 kilos (216 pounds), Crowe added that he's still "clawing [his] way back from" his higher weight.
On working with Gosling, 35, Crowe said that the actor – who we're used to seeing in dramas – constantly kept the laughs coming on set, adding that the father of one made him laugh at inappropriate times more than he ever has in his career.
"That kid is a comic genius. He's great company. He's really smart. He loves what he does and he asks all the right questions," Crowe added. "Working with him was such a treat. The kid just knows how to make me laugh. He's very, very funny."
