HE'S the "guru of gurus". He's a "master of the form and a servant of the craft". He's "legendary", according to the Washington Post, and "brilliant", according to Newsday, and "empowering", according to Movieline.
He is, in fact, Hollywood's most wanted screenwriting teacher, and has been for 30 years.
"Everything I know about story structure," says Paul Haggis, the Oscar-winning writer and director of Crash and Million Dollar Baby, "I learned from Robert McKee."
Some creative writing teachers can name a handful of successes.
With Robert McKee, the list goes on and on. There's Akiva Goldsman (A Beautiful Mind) and Ed Saxon (The Silence of the Lambs) and John Lasseter (Wall-E) and Andrew Stanton (Finding Nemo) and Jane Campion (The Piano) and Peter Jackson (The Lord of the Rings).
And then there are the writers for TV. The writers, that is, for The Sopranos, and Sex and the City, and Ugly Betty, and Six Feet Under and Boardwalk Empire and Game of Thrones.
These are just some of the 55,000 people, who include Joan Rivers, John Cleese, Russell Brand and David Bowie, who have done a story seminar with Robert McKee.
The seminar used to take three days, and now takes four.
It covers, if his book Story is anything to go by, the elements of story, like structure, setting, genre and character, and the principles of story design, like crisis, and climax and resolution.
If this makes it sound like a formula, it isn't.
"Anxious, inexperienced writers obey rules," says McKee in his introduction to the book.
"Rebellious, unschooled writers break rules. Artists master the form."
Four days (and $A1100) isn't much to invest if you're planning your career as an Oscar-winning writer and director, but it's quite a lot if you're a journalist who's heard a lot about the guy and just wants to see what he's like.
Luckily for me, and about 100 writers, or budding writers, at the Barbican the other day, Robert McKee also sometimes gives talks.
This one was part of the London Screenwriters' Festival's monthly London Breakfast Club.
There was coffee. There were croissants. There were a lot of hopes and dreams.
Robert McKee, it was clear from the big photo projected on the stage, and also from the figure who walked up to the lectern, has very bushy eyebrows.
For a moment, I couldn't think of anything else.
But when he started speaking, I forgot about his eyebrows, and the second croissant I'd meant to grab but hadn't, and thought only about the words.
"Story began," he said, "the moment Mother Nature and human nature went their separate ways.
The first human thought was something like 'I am', and the second thought was 'some day, I shall not be'.
As we became aware of the passage of time, and the brevity of it, and the end of it, we quickly became aware that just living does not teach you how to live."
There is, as Dr Johnson knew, nothing like death to concentrate the mind, but I hadn't expected a talk on screenwriting to start with death.
From death, it went on to survival, and how the human mind can 'rationalise any evil act'.
There is, said McKee, 'no structural difference between cutting someone up in traffic and cutting off their head'.
All of us, he said, are struggling to answer Aristotle's question about how a human being should live their life.
Living, he said, is chaotic and painful, so human beings began to create stories. Culture, he said, 'is our great nest'.
Any of us who read or write know that stories are what we create to make order out of chaos, but I'm not sure I've ever heard the idea presented with such urgency, or power.
The challenge, said McKee, was to 'create an emotional truth of what it is to be a human being'.
There is, he said, a notion he finds repulsive that stories, or films, are 'just entertainment'.
Entertainment, he said, was going into the ritual of story so that time vanishes.
When a society has weak storytelling, he said, life rots. We need storytelling to shine a bright light into the corners of society and express the truth of what it is to be a human being.
I wish I could tell you everything he said. I wrote down nearly every word.
This, it turned out, was about as far from 'how to get on in Hollywood' as you could get.
This, it turned out, was about how to ditch the careerism, and the cynicism, and the formulas, and write with integrity, and truth.
It was, I told him when we met for a cup of coffee afterwards, like a religious experience.
"It is kind of like my religion," he said.
"I think these people need to be reminded of why they do what they do".
"I do not teach people how to do anything," he said.
"I simply teach what is.
"Art," he said, speaking for all true artists, and for everyone who benefits from art, which is pretty much all of us, "softens the sharp edges of life, and helps us get through our lives."
