Having convinced America aliens were invading in 1938, Orson Welles mused on art-as-deception in this 1974 pic considered his last classic.

Jumping off from a BBC commission about art forger Elmyr De Hory, Welles uses blink/ miss editing to stitch up a mischievous mash of mock-doc, magic show, lecture and comedy.
