There are others. Mythbusters did a pretty good job debunking the shoot-the-hat-off thing, but I saw another example. My late brother wanted to have a cool bullet hole in his hat one time, so he put it on a fencepost and had at it with a 7x57. The problem with that was that it caught a bit of fencepost on the way out and it blew the back of the hat away. Oh, and it didn't fly anywhere.
What else? George Plimpton was an extra in, I believe, El Dorado, and wrote about what they had to do to get him blown into a wall by a shotgun. Body harness and a cable jerk from a hidden winch. I shall insist on all of my opponents being so equipped.
Then, for pure realism, there's this one from The Matrix Trilogy. I'm still working on the shoot-the-automatic-weapon-while-doing-a-cartwheel thing. I can shoot, I just have a hard time with the cartwheel.
You’d almost think that they were more concerned about spectacle than realism.
The worst scene from the Matrix was when Keanu shoots his gun, the camera follows the bullet on its trajectory and the bullet is flying through the air with the casing attached.
