Robert De Niro suffered an off-set leg injury while shooting for Martin Scorsese's new film Killers of the Flower Moon in Oklahoma.
In an interview with Indie Wire, the 77-year-old revealed that he tore his quad somehow.
Speaking about how he got the injury, he said: "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."
In the upcoming film, he plays cattleman William Hale and shared that the injury will not affect his performance.
"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."
Killers of the Flower Moon, which also stars Leonardo DiCaprio is based on the non-fiction book by David Graan which investigates the murder of members from the Osage tribe in the US.
