Welles’ meditation on charlatanism is in itself a great magic trick. Stare at it too hard and you’ll realize it’s just a mish-mosh of someone else’s footage, plus whatever other crap he had lying around his editing room. But with enough smoke and funhouse mirrors it feels like a full meal. Disc Two of Criterion’s release has some wild documentaries. One is a “straight” version of the events detailed in “F For Fake,” the other is a look at Welles’ late career, his production manner during this time and the projects he lorded over simultaneously and never completed.
