Blonde director Andrew Dominik has admitted he "swore off" the project on several occasions and said he had doubts about bringing the movie, which was over a decade in the making, to the big screen.

The 54-year-old filmmaker, who has penned and directed the adaptation of Joyce Carol Oates' novel, said the long-awaited film almost broke his heart.

Speaking to IndieWire, he said: "There were many times I swore off Blonde. When it breaks your heart, you want to let go of the damn thing, but it just wouldn't leave me alone."

Ana de Armas plays the iconic role of Marilyn in the movie and Dominik revealed that the actress surpassed his own expectations with her portrayal of the late Hollywood legend.

"She was always better than I thought she was going to be. I mean, I couldn't have shot that movie in 45 days without her because she was the rock around which the whole thing had to function."

Opening up about the tight production schedule, Dominik said: "It's less boring. I have done stuff where you shoot take after take of a 15-minute dialogue scene and you start to bore yourself.

"There's something about having to operate from instinct, particularly for the crew. There's a lot of camera protocol that I try to dispense with and just throw them in before they're ready, and it's amazing how good they are on instinct."

He continued: "You'll see a focus puller who doesn't know what the actor's going to do, and they pull focus really well when they don't know what's coming. Then on the next take, when they do know what's coming, they're not as good."
