In 1970 Stanley Kubrick sent a letter to James Aubrey at MGM threatening to stick a femur bone up his ass if he dared fuck with Kubrick's masterpiece, 2001: A Space Odyssey.
I have no doubt he was 100% serious.
Kubrick was certainly one of the directors--and maybe the GOAT. What the great directors, and all great artists, have in common is this: they care more abut their art than life itself.
They will inflict pain, they will maim, and they will put their lives and the lives of others at risk. AND (I suspect) they'll even kill.
But that's why they're top-tier. Because very few people have this sort of love and compulsion for their work. It's not like they can turn it off. They're compelled to create at ANY cost.
You may say (in job interview for example) that you're "passionate" about your work. And you may say you're "dedicated". But you're not passionate dedicated like Kubrick. And you're not going to make a movie as good as his movies, because you don't have that passion.
This is probably for the best. These people (despite their carefully crafted public personas) generally aren't happy or well-adjusted and you probably have a shot at a normal fulfilling life. So take the easy route man.
But if you have that compulsion for greatness, then you'll know. When your art is threatened you'll act like a mama bear protecting her cubs--or a femur wielding Stanley Kubrick.
To outsiders this looks like insanity. And it IS insanity.
But it's funny how the public forgives insanity in service of art.
Early in my career I had the pleasure of working with one of the all time great cinematographers (aka a "DP" or Director of Photography). He did huge movies, had a fist full of Oscars, and was very nice and decent person--that is until somebody fucked with his art.
If something wasn't perfect, like a lighting stand peeking in the corner of the shot, he'd scream (in his Mexican accent) "YOU RUIN MY ART!" and storm off set.
One day we were shooting a house exterior. There was a power line running into the house from the utility pole on the street. It connected right at the peak of the roof, and it was fucking up the DP's composition.
He asked the producers to get it removed, but they said no for budget reasons. So this guy took a pair of bolt cutters from the grip truck, then fired up the Condor (a boom lift), and went up to cut a live power line.
Me and the crew are on the ground. We're all screaming variations of "DON'T DO IT YOU'LL DIE!"
And he's shouting back "YOU RUIN MY ART I'LL FUCKING DO IT YOU RUIN MY ART!"
This wasn't a bluff. We knew he was serious. He was willing to take his own life to get a perfect shot. He had to do it. Because that's what being an artist means.
Again, this guy was The Best. He was the GOAT.
He was GOATED not because of some drive to succeed, but because he couldn't help himself. He couldn't NOT put his life at risk for his art. Everything he made had to be perfect, no matter what the cost.
The producers knew he was serious too. So (at great expense) they delayed production by a few days, got the power line removed, and eventually he was able to get his perfect shot.
This is a good lesson if you ever find yourself working with serious artists. They don't like it when someone fucks with their art. In fact, they can't HELP but not like it.
And they'll do seemingly crazy things to protect it.
That's how you know that they're serious about their work.
And if you aren't serious about helping them protect the art, then maybe you should find another profession.
But whatever you do--no matter what--don't fuck with their art.
Because you might get a femur shoved up your ass.
