I haven't finished thinking this through, but maybe a work's creator has installed precisely as much backstory as is necessary to understand a character, which is why prequels mostly* don't work—though sequels can be fun.
*Jean Rhys excepted.
Though when it comes to storytelling variants, nothing is better than a really good DC imaginary novel.
She was walking toward me one afternoon on a UES sidewalk and I tripped on one of those low metal tree railings because I was too busy gawping at her, and she was very sweetly concerned for my well-being and probably I told her that I worshiped her.
In 2014 I saw her as teenage Katrin in I Remember Mama, and it was a superbly lovely performance.
In 1991 I sent a note to Audrey Hepburn c/o Lincoln Center to tell her that a friend of mine who was to have attended her Film Society gala was too ill to attend, and she wrote him a note on her UNICEF stationery and sent it from Switzerland.
That's my Audrey Hepburn story.
"I missed you at Lincoln Centre [sic]! Get well soon!"

"What's the siren song for? / What is my chaise longue for?"
Always happy to point out to Wizard of Oz watchers that the WWW's skywriting is addressed not to Dorothy (i.e., "Surrender, Dorothy") but to the citizens of Emerald City (i.e., give Dorothy to me). It originally read in full "Surrender Dorothy or die."
Also always happy to brood over the fact that the Witch's head monkey gets better billing than Aunt Em.
How many viewings did it take me to figure out what the Munchkin barrister says after "This is a day of independence / for all the Munchkins and their descendants"?
Peggy Ashcroft, who had a brief affair with Robeson ("Well, wouldn't you?" —Guys and Dolls), registered her displeasure that Robeson, appearing with her in the Savoy Theatre, was not welcome in the adjoining hotel.
Robeson concludes his (amazing) performance of "Ol' Man River" in the '36 Show Boat with a huge grin, and I've never been sure if it's Joe fully embracing existence or Paul acknowledging how good he is.
Unless you're an attorney or a particularly scholarly scholar, you may, in quoting published material, capitalize a lowercase letter or lowercase a capital letter at the beginning of a quoted bit, as it serves your own text, without the use of brackets.
In other words, don't do this:
Dreyer says that "[u]nless you're an attorney or a particularly scholarly scholar"...
Also, though all intratext deletions must be called out with ellipses, no quote needs to begin or end with them.
P.S. An actual film of L. Frank Baum's actual novel The Wonderful Wizard of Oz is an interesting idea. A film of The Marvelous Land of Oz—you know, the one in which the boy Tip is actually Princess Ozma—could rock.
And now that you* mention it, I'm shocked no one's ever gotten around to filming Geoff Ryman's Was.
We are told that it was by Bob Denver's insistence that "and the rest" was changed to "the Professor and Mary Ann," and that when the studio balked at rerecording the song he said "Include them or remove me."
I did not know that Dawn Wells had her turn as the lead in They're Playing Our Song on Broadway. (And I read just now that she spent years touring the country in musicals.)
