Keanu Reeves mightve looked bad-ass during his action sequences in the John Wick franchise, but according to the actor, his skillful moves came with a stomach turning price.

While attending a 10th anniversary screening of the franchises first film on Sunday in Los Angeles, Reeves, 60, got candid about how performing the physically demanding stunts as the gun-toting hitman cost him his lunch at times.

I had so many wonderful teachers and guidance, and worked with so many talented actors, actresses and stunt people in the sense of its such a dance and collaboration and cooperation, he said during a panel discussion with co-star Ian McShane, co-director Chad Stahelski and producer Erica Lee, People magazine reported .

Reeves added, So theres a couple of times where you throw up or puke or whatever, but thats what makes it good!

John Wick, which follows a retired assassin who is thrust back into the criminal underworld after being harassed by a crime lords son, first premiered in 2014. The box office hit spawned three sequels, with John Wick 4 most recently hitting theaters in March 2023.

Reeves deemed the film franchises fourth installment the hardest physical role hes ever experienced in an interview with Total Film in January 2023.

John Wick: Chapter 4 was the hardest physical role Ive ever had in my career so far, he told the publication. They really trained me up to be able to have what we call the toolbox.

The Matrix alum, who made his professional auto racing debut last month at the Indianapolis Motor Speedway, gushed over taking his skills behind the wheel to the next level for the high-adrenaline film.

We took the car-driving to the next level, which I really enjoy, he explained.

Reeves added, Theres 180s, forward-into-reverse 180s, reverse-into-forward 270s, drifting so it was really fun to get a chance to learn those skills, and to play.
