"Bullet Train" star Aaron Taylor-Johnson said that he lost a chunk of his hand and passed out from a stunt injury while filming the blockbuster film.

On Monday, Taylor-Johnson joined the rest of the cast at the Los Angeles premiere of "Bullet Train," a movie that follows several assassins who are on colliding paths on a train. In the movie, based on a Japanese novel of the same name, the 32-year-old actor plays Tangerine, one of several assassins in the movie.

In an interview with Variety at the premiere, Taylor-Johnson said that he received a "war wound" while filming the movie, which meant he had to go to a hospital.

"I was on some crazy mad Keto diet," the "Bullet Train" actor said. "Because I got all scrawny and lean for this, so I basically had low blood sugar levels. We were in a fight sequence and I get dropkicked across the room. And the one sharp bit of the corner, where there wasn't any padding, took a chunk out of my hand. And I literally went, wham, passed out."

Taylor-Johnson continued: "And then I came back and was like, 'Should we go again?' And they were like, 'No, no, no. You gotta go get stitches at the hospital.' So then I spent the night in the hospital."

The "Kick-Ass" actor said that he still had "a lot of fun" despite the injury and praised director David Leitch.

"You know, when you sign up for a David Leitch movie, you know you gotta get a couple battle scars. Some war wounds," Taylor-Johnson said. "David Leitch gave us so much room to improv and adlib, and we really just wanted to make these characters pop. I mean, it's such a heightened reality, the tone of this movie. [These characters] are so bombastic, so you wanna make them lifted and pop. So hopefully we've done that."

Leitch recently told Yahoo that Brad Pitt, who plays the lead character, Ladybug, did 99% of his stunts for the movie. However, unlike his younger costars, he sustained no on-set injuries.

Pitt told The Hollywood Reporter on Monday: "I'm just skilled at dodging, I guess."

"Bullet Train" premieres in theaters on Friday. The movie also stars Sandra Bullock, Joey King, Brian Tyree Henry, and Andrew Koji.
