Stephen Colbert asked Keanu Reeves all the important questions on Tuesday’s “The Late Show”, including: “Who would win in a fight: Neo or John Wick?”

Reeves wasn’t keen on his two characters — the hero from “The Matrix” and the main character in the “John Wick” series — battling it out.

As the actor, who appeared on the talk show with his “Bill and Ted” co-star Alex Winter, initially refused to reveal who would win the fight, Colbert asked: “What if Neo accidentally killed John Wick’s dog?”

“No! No! They wouldn’t fight!” Reeves insisted. “But maybe John Wick would try and help Thomas Anderson out in the real world. Maybe against the machines.”

“Alright, done. That’s canon now,” Colbert laughed, as Reeves said it would be “multi-dimensional.”
