The 59-year-old actor shared how he broke his kneecap while filming. Reeves, who is known for his action-packed filmography with movies like The Matrix and the John Wick series, revealed how he was felled by a rather innocuous thing.

Colbert asked Reeves, “What happened? Who got to you?”

The actor replied playfully in a tough guy voice, “No one got to me,” adding, “Accident got to me.”

“Were you jumping from building to building? Were you doing a cartwheel past razor blades? What were you doing?” Stephen further probed.

“No, Stephen, I was walking into the dressing room, a room. I will tell it quick,” Keanu explained.

Keanu shared that it happened while he was filming a scene for an upcoming comedy titled Good Fortune with Aziz Ansari, and Seth Rogen. The three of them were in a cold plunge, and Keanu was enjoying it. After they finished, he started doing the “cold shuffle” in a room with protective carpets. Unfortunately, his foot got caught in a pocket as he was doing so.

Keanu stood up to demonstrate what had happened by walking in front of Stephen’s desk and showed how his knee gave way. “And I spiked. Like, spiked,” he said, mimicking what had happened to him. “Just drove it into the ground.”

“My patella, kneecap, cracked like a potato chip. But I didn’t know that. But then once my knee was blowing up,” Keanu went on.

“Comedy is hard, man,” Keanu added as a joke.

“This was not an action film with Aziz and Rogen,” Stephen clarified once again.

“No, it was comedy,” Keanu confirmed.

“Welcome to my life,” Stephen joked.

Keanu had been spotted filming while on crutches in January this year with an ice pack on his knee.

Good Fortune not only stars Aziz Ansari but will also be his directorial debut. The actor wrote and co-produced the movie which also stars Sandra Oh and Keke Palmer.
