The Making of Quixote

[bruttenholm]

A few years ago, a famous french director did something close... He camouflaged his film by pretending his first assistant was the director. So the official director wasn't around when journalists visited etc., when someone exterior to the shoot asked, everybody on the crew played the game as if the assistant was the director. And then the film was unveiled as the new film of the famous director when it was shown at a festival.
I guess that's only achievable if you work on a small film...
