The couple that works together stays together – at least that’s the case for Anne Hathaway and husband Adam Shulman.

Hathaway, 32, stars in the new film Song One, and one of her collaborators just so happened to be Shulman, who co-produced the indie drama from director Kate Barker-Froyland.

“At first, I was curious how it would go. People always say don’t work with your spouse,” the actress told PEOPLE Tuesday at the film’s N.Y.C. premiere, sponsored by The Cinema Society and Tod’s.

“But I loved working with him. He’s really good at this, and he’s a wonderful producer. And I feel like I actually learned a lot from him in the process.”

And Shulman wasn’t just a positive presence on set for his wife: Hathaway’s costar Johnny Flynn, who plays her love interest, says he’s taking both acting and relationship cues from the new producer.

“They’re, like, fantastic. I’m married as well, but I was watching them and going, ‘Oh, that’s how you do it!’ ” musician-actor Flynn told PEOPLE. “They’re so supportive to each other It was lovely, him being there.”

Hathaway and Shulman, 33, tied the knot in 2012 after dating for four years.

“I didn’t realize that I was keeping a part of myself protected, and it’s kind of all on the line now,” the Oscar winner recently told Savannah Guthrie of their marriage. “I’m his, and he’s mine.”
