Of course, far left film critics aren’t immune to this phenomenon, either: consider all of the modern-day critics who laugh at Charlton Heston playing a Mexican policeman in Welles’ last American directorial effort, 1958′s Touch of Evil, without the knowledge that Heston, at the height of his career as a box office superstar, insisted to Universal that either Welles directed the film, or he wouldn’t star in it. And how in-your-face a gesture it was to American audiences for Welles to cast the WASP-y Heston as a sympathetic Hispanic figure of authority.
