Robert Wise(1914-2005)

After collaborating closely and happily on the editing of Ciudadano Kane (1941) with Orson Welles, Wise was assigned to edit El cuarto mandamiento (1942). When Welles left the country after finishing that film, RKO wanted Wise to edit it, making changes that Wise knew Welles wouldn't like. He initially refused because of his respect for Welles' vision of the film, but eventually relented and allowed RKO to put him in charge of a drastic editing of "Ambersons" that would result in a new ending and over 40 minutes of Welles' film being lost forever. A furious Welles held that against Wise for more than 40 years, until they reconciled publicly in 1984 by shaking hands on stage when the Directors Guild of America honored Welles with its Lifetime Achievement Award.

Not true there was a cabal preventing Orson [Orson Welles] from making more films. He simply never fulfilled himself after that magnificent start; his own fault - lack of self-discipline.
