A rep for The Irishman actor tells E! News De Niro suffered "a mild leg injury" amid ongoing production of the Apple+ thriller.
The statement continues, "While at his on-location home in Oklahoma for the filming of Martin Scorsese's Killers of the Flower Moon, Robert De Niro injured his quadriceps muscle which will be treated medically in New York. This will not affect production as he was not scheduled to film again for another two weeks."
Production for the Scorsese film began in late April, with the cast relocating to Osage County in Oklahoma for the Western. According to IndieWire, Scorsese released a statement announcing the April 19th start date, sharing, "To be able to tell this story on the land where these events took place is incredibly important and critical to allowing us to portray an accurate depiction of the time and people."
Screenwriter Eric Roth based the screenplay on author David Grann's book, Killers of the Flower Moon: The Osage Murders and the Birth of the FBI, which detailed the Osage peoples' battle for land rights after oil was found. There were a string of murders, later named the Reign of Terror, during the power struggle, causing the FBI to intervene.
De Niro plays one of the main suspects, a ranch owner named William Hale. Meanwhile, DiCaprio portrays Hale's nephew, Ernest Burkhart, who is married to Lily Gladstone's Mollie, an Osage woman.
This is the latest movie the actors have starred in together, having previously worked on This Boy's Life and the Scorsese directed short-film The Audition.
They are joined by Fargo's Jesse Plemons, and numerous other actors, most of whom are indigenous. Additionally, multiple indigenous people are serving as consultants on the film.
According to IndieWire, DiCaprio and Scorsese met with the Osage community and Chief of the Osage Nation Geoffrey Standing Bear prior to production. Standing Bear released a statement voicing support for the movie and the influence it will have on the Osage Nation.
