As one might expect, the characters themselves are more important than the thin plot--Ferrand trying to keep his production on track when his emotionally unstable leads, Alphonse and Julie, make the mistake of sleeping together for just one night. Full of in jokes and cross-references, DAY FOR NIGHT is ample proof that what goes on behind the screen is often of more interest than the film itself. Paradoxically, it is also one of Truffaut's least personal films, as he hides behind his alter ego Ferrand and interacts only on the most superficial levels with his cast and crew. By the film's end, it is Ferrand whom we know least.
