Conversation so far:
When was the first film Jacques Cousteau made?
The two neighbors took the first ex-aequo prize of the Congress of Documentary Film in 1943.
What was special about this film that it won an award?
1943, for the first French underwater film: Par dix-huit metres de fond (18 meters deep), made without breathing apparatus the previous year in the Embiez islands.

Question: Did they make another film after that?
Self-contained rewrite: Did Cousteau make another film aside from the two neighbors?
