Adding that Dion was a “really good person to act with,” theOutlanderstar continued, “The same goes for Priyanka. [She has] such a great heart, she’s the heart of the movie, I think. And I’ve got so much admiration for both of these brilliant women who are at the top of their game.”

When asked if he gave Dion — who made her acting debut in the film — any advice, Heughan admitted, “I don’t think she needs any help.”

“She’s brilliant at what she does. She’s so funny,” he added. “She’s playing herself in the movie, she’s got her own love story of her own in real life. It was so touching to work with her.”
