Robert De Niro learned a new language for his Oscar nominated film Killers of the Flower Moon and it really took a lot of his effort.
During an Interview with PEOPLE magazine for this week's issue, The Irishman actor's costar Lily Gladstone revealed the amount of struggle he went through for his character, William Hale, in Killers of the Flower Moon, which depicts the harrowing true tail of terror in 1920s Oklahoma.
De Niro portrayed the role of a white man, who in order to steal the oil-rich land from several Indigenous Osage people, orchestrates their murders.
“He was spending every waking minute trying to get it right,” recalled Gladstone about the Taxi Driver actor.
She further revealed that De Niro was trying to hard to learn Osage language that “His partner, Tiffany [Chen], has joked that he would start speaking the language in his sleep."
De Niro also confirmed Gladstone's revelation about his partner Chen, saying, “She heard me mumbling. I was constantly going over and over. I couldn’t stumble through that [onscreen]. You have to know it.”
The director of Killers of the Flower Moon, Martin Scorsese, who has collaborated with De Niro on at least 10 films, also gushed over the actor saying, “When Bob commits, he starts digging in with research, questions about absolutely everything, from what the character wears to what he eats for breakfast.”
"The search and the discoveries never stop," added Martin of De Niro.
De Niro’s performance in Killers of the Flower Moon garnered huge praises from both critics and viewers, and has earned him his eighth acting Oscar nomination.
The 80-year-old actor also bagged the Oscar nomination for producing Best Picture nominee The Irishman, making him one of 17 artists in Hollywood, who have eight or more acting nominations for Oscars.
