When it comes to action sequences, there are precious few movies that can hold a candle to 'John Wick' or 'The Matrix', and that's down to Keanu Reeves.

Why? Well, for one, the training regimen he puts himself through for each of these movies is unlike any other you'll see in the industry today. In fact, Reeves regularly goes to a training school in California - known as Taran Tactical - that has become famous for posting videos of Reeves during his training.

The videos show Reeves in live-round exercises - that's where he's actually shooting real bullets, not blanks like they do won set - barreling his way through the course like he's actually John Wick. In fact, here's one from 'John Wick: Chapter 3 - Parabellum', where he trained with Halle Berry.

Expect to see another one of these videos pretty soon, as Reeves was at Taran Tactical earlier this week to begin his training for both 'John Wick: Chapter 4' and 'The Matrix 4'. He's even got the trademark Keanu Reeves Respectful Hover-hand going on, too.

Currently, both movies are set to come out on the exact same day - May 21st, 2021 - but odds are that at least one of the release dates will change because somebody's got to blink and change.

If we were taking bets, the odds are that 'The Matrix 4' will change release dates as the special effects work will undoubtedly take much longer than 'John Wick 4'.
