Here are some that aren't as common, mostly interviews, many book-length. Many of these are from other perspectives, but touch heavily on story creation and screenwriting. They're old in many cases (from my library built up over many years), and hard to find, but well worth it if you can:

"Schrader on Schrader"
"Scorcese on Scorcese"
"Gilliam on Gilliam"
"Cronenberg on Cronenberg"
"Lynch on Lynch"
"Levinson on Levinson"
"Reel Conversations"
"Raymond Chandler Speaking"
"Oscar Winning Screenwriters on Screenwriting"
"Screenwriter's Masterclass"
"Moviemaker's Master Class"
"Good Scripts, Bad Scripts"
"A Cut Above: 50 Film Directors Talk About Their Craft"
"Film Makers on Film Making" Vol. 1 & 2"
"Hollywood Directors 1914-1940"
"Hollywood Directors 1941-1976"
"Hollywood Speaks, An Oral History"
"Interviews With Film Directors"
"Inside Story"
"Kings of the B's"
"The Movie Brats, How the Film Generation Took Over Hollywood"
"The Reel Tinsel"
"Schmucks With Underwoods"
"The Director's Event"
"The Film Director As Superstar"
"Take 22, Moviemakers on Moviemaking"

Wow, thanks, all! This is a terrific place to start. I do have some of these, but am excited to see so many other excellent looking resources.

Hope I can return the favor sometime.

Thanks again,
Jill

Quickly wanted to add that one book I found utterly fascinating and invaluable was George Stevens, Jr.'s "The Great Moviemakers of Hollywood's Golden Age." From script to screen, the masters tell their stories, secrets, observations. It's just great. I am also composing a screenwriter's booklist for my workshop, which I'll pass on when done. It's a combination of the book titles culled here and also from my shelf and the shelves of my pals. Cheers, J
