Robert De Niro has spoken of the "excruciating" leg injury he suffered while shooting a new Martin Scorsese film.
The Taxi Driver actor, 77, said he tore a muscle while filming the director's new flick Killers of the Flower Moon.
He said the accident was "unexpected" yet "manageable" during a chat with IndieWire ahead of the Tribeca Film Festival.
"I tore my quad somehow," he explained. "It's just a simple stepping over something and I just went down. The pain was excruciating and now I have to get it fixed.
"But it happens, especially when you get older, you have to be prepared for unexpected things. But it's manageable."
De Niro explained that his role in the upcoming film doesn't require a lot of physical movement so filming was able to carry on as normal.
The actor went on: "What I'm doing with Scorsese in Killers of the Flower Moon, I'm pretty much a sedentary character in a way.
"I don't move around a lot, thank god. So we'll manage."
"I just have to get the procedure done and keep it straight in a certain position and let it heal."
De Niro reportedly flew across the country on Thursday evening to see a doctor near his home in New York.
A source told TMZ that the Oscar-winning actor was due to have two weeks away from filming, and his trip to NYC was a scheduled one, but he saw his doctor whilst there.
Killers of the Flower Moon also stars Leonardo DiCaprio, Jesse Plemons, and Lily Gladstone and is being directed by Scorsese, De Niro's long-time collaborator.
This is the ninth time that the pair have worked together, the most recent being last year's Oscar-nominated The Irishman.
The film is based on the true story of a Western cattle rancher and extortionist during the 1920s
De Niro's character Bill Hale was so desperate to control the oil rights on his stolen land, that he became the mastermind behind the deaths of his nephew's wife, mother-in-law and other members of the family.
Hale's campaign of blackmail and murder was eventually investigated by the FBI.
In a letter to J Edgar Hoover, the special agent in charge of the case said: "Hale became a millionaire, who dominated local politics and seemingly could not be punished for any of the many crimes which were laid at his door."
