Good Morning America’s Chris Connelly sat down with Lily Gladstone and Leonardo DiCaprio about their new acclaimed drama Killers of the Flower Moon, and Leo called his co-star “electrifying.”

He enthuses, “I’ve never seen Martin Scorsese meet somebody for the first time and say ‘That person is doing the role higher — I want her to be our partner on this film."”

The based-on-real-life period drama is DiCaprio’s sixth film with Scorsese, whom he called “a national treasure,” but in the eyes of many critics, 37-year-old Gladstone steals the show in Flower Moon for her performance as Molly.

Leo said of his Native American co-star, “the respect … and dedication that she gave to telling the story through the Osage viewpoint the right way. She kind of represented her grandmother in a lot of ways.”

Speaking of Gladstone’s grandmother, she recalled how excited she was to learn Lily was making a movie with De Niro and Scorsese, but had no idea who DiCaprio was. “‘Who?"” Lily recalls with a laughs. “So I pulled out Titanic.”

Killers of the Flower Moon is now playing in theaters, on its way to streaming on Apple TV+.
