La nuit americaine, 1973 Multiple takes

As Severine (Valentina Cortese) has more and more trouble remembering her lines (blowing several takes), Ferrand eventually writes her lines on pieces of paper that can be stuck up on the set out of sight of the camera, so that she can read them. It doesn t really work here. However, Truffaut used the same trick for himself when he was having trouble remembering his English lines in Close Encounters of the Third Kind (1977).
