A very young actor, hired by the production to play in the series, once called director Gilles Grangier in a very nasty and provocative manner because he did not receive the script fast enough. Grangier then told him that this young actor was not needed anymore. Grangier directed for the first time for the TV industry and was a bit scared about the pace of shooting, but who eventually made it.
Gilles Grangier tells in his biography that the shooting was made without sound at all because the story was supposed to take place in a time where there was no cars. And the shooting place was very close to a high traffic avenue.
