 Michel Gondry (qv) had a unique system of controlling his camera  operators while shooting by use of a headset for Michel and  earpieces for the two operators. He would speak to them (in french)  while cameras were rolling and the actors were doing their parts, so  Gondry could have a say on all angles no matter where the actors  were. This results in a large degree of spontaneity, since the  actors could decide while in character whether to have an entire  conversation sitting on a couch or get up and walk to a window.  Kate Winslet (qv) said that she felt this freedom enhanced her  performance, and that sometimes they would do different takes of the  same scene completely differently, based purely on gut feelings for  what the characters might have done.
