As a teenager, I had a real fondness for this Western-Comedy from Robert Aldrich, not usually known as Mr. Funny Guy. But Gene Wilder was a god to me in the 70s, and for all of the film's other flaws, his performance is inspired. The film takes off as soon as he and Harrison Ford meet cute, with chiseled Ford making a great straight-man to Wilder's lovable schmendrik. The "Indian" scene still holds up well, particularly the dance, but the film's final 20 minutes are so are devoid of that magic of the epic road trip.
Though this is just the 40 minute work-print of selected scenes that Welles edited, there's no doubt that this is some sort of masterpiece, and I do hope the crowd funding campaign is a success. If the film-within-a-film is meant to be a dig at "art cinema" of the day, Orson has nailed it.
