Letters of Note has reprinted the 28-page Jeffrey Katzenberg memo dated January 11 1991, "Some Thoughts On Our Business." It's a great longread:
In the dizzying world of moviemaking, we must not be distracted from one fundamental concept: the idea is king. Stars, directors, writers, hardware, special effects, new sound systems… all of these can have a role to play in the success of a film, but they must all serve as humble subjects to the supremacy of the idea....The irony, as the above LA Times story notes, is that if anyone succeeded in this path it wasn't Katzenberg's next venture, Dreamworks SKG, but rather Pixar ... which Disney acquired.
This is the key for controlling our destiny -- to have the courage to search out authentic, great ideas… and then have the steadfastness to control the material that is subsequently developed.
If the idea and the screenplay are strong, then it is possible to hire a less established star and a less established director and as a result be less of a hostage to the marketplace. Or, conversely, an idea and a screenplay can be so great as to attract major talent, who will be sufficiently excited that they will agree to terms that are acceptable to us.
