At the UK premiere, Dakota told the press about how much fun she had on the set.

“Even though it was super emotional and tense and all of that, we all had an amazing time and I think the fun that we had was the key,” Dakota said. “We became like a small family and had fun together and laughed together, and then we’d know when it was time to be serious. And that meant it wasn’t a challenge to go to work every day, where we were gonna be depressed and sad, and everyone really looked forward to it.”

FYI: Dakota is wearing a Stella McCartney gown, Jimmy Choo shoes, and a Lanvin clutch.
