Welles claims that Michael Salkind produced the G.W. Pabst version of 'Don Quixote' (1933), which he calls 'Don Quixote of Chaliapin' (because Feodor Chaliapin was the star). In fact, Michael and his son Alexander worked for many years to produce a film of the Bruno Franks novel "A Man Called Cervantes" with King Vidor as director. That partnership dissolved and Vincent Sherman eventually directed the project in 1967 under the title, 'Cervantes' (aka; 'Young Rebel'); five years *after* Welles story of meeting the Salkinds took place. It is entirely probable that the Salkinds discussed their ongoing Cervantes project with Welles in the early 60s, but by 1981 Orson has conflated that story with the Pabst 'Don Quixote' film, as the Salkinds actually had nothing to do with the production of the 1933 film.
This movie was left unfinished by Orson Welles. In the 2000s, the Munich Film Museum edited together the complete footage into an 82-minute cut of the Q&A session.
Since cinematographer Gary Graver had to change film cartridges approximately every 10 minutes, this created breaks in filming, which are noticeable in the final cut.
