If you go all the way back to 1991 Keanu trained with SigArms, where i later worked for at the SigArms Academy, to learn the sequence doing the FBI outdoor qual course with a P226 and a shotgun. He did a great job for a Canadian actor that had no firearms experience at all up until then - watch the start of Point Break - pretty good for the day.
Now, with the latest John Wick film, he's been putting in hours into learning modern gunfight techniqes - even off the wall ones like the center axis relock he used in John Wick so well.
He's training for a few films, Rain, The Bad Batch, and John Wick 2.
Nice to see some actors can bring the noise.
