Right, but the behind-the-scenes antics affect the on-screen performances.

For instance, Matt Damon DID NOT train in martial arts as assiduously for the Bourne series as Keanu Reeves did for the Matrix and John Wick. As a result, he could not get the choreography down correctly for the fight scenes -- his timing and positioning was almost always off. This isn't some hidden knowledge, this was in the behind-the-scenes footage and in plenty of interviews.

The result is that Damon's lack of dedication to the craft OFF-SCREEN impacted how the fight scenes had to be depicted ON-SCREEN. So what did we end up with? An era of shaky cam, quick-cuts, and fast-edits to hide the fact that Damon couldn't fight. This lack of off-screen dedication helped dampen and ruin the appeal in many Hollywood fight scenes, where shaky cam was a solution for actors who were incapable of learning the choreography correctly or lacked the physical skill to play the role believably.

Uma Thurman had the same problem in Kill Bill (again, this is no surprise, as they talked about it extensively in the behind-the-scenes footage), so they once again used a lot of editing tricks and Zoë Bell to compensate -- thankfully Bell is a dead ringer for Thurman, and had a similar build and height, so Bell could do most of the stand-ins for the fight scenes and almost no one noticed.

Now some people don't care about these things -- they just sit down and turn their brain off and enjoy whatever is fed to them, but I do care about these things because dedication to the craft and the pursuit of suspending the audience's disbelief shows a level of commitment to excellence from the filmmakers and crew that I highly respect.
