When I was a kid I used to watch from time to time these TV programs on French TV Channels about Cousteau and his team. I must admit that when watching The Life Aquatic I feally felt that they were all dressed like Cousteau and presenting themselves on the boat like Cousteau and talking to the camera like Cousteau , etc... Dressed in blue with the red "bonnet" hat and the grey beard (or at times shaven) is really how I rmemeber Cousteau.
Now I am not sure how many here know about Cousteau as this has to do with the French Culture from 1970s... but I would appreciate if anyone of you has heard of anything. I know in the movie they comment on Cousteau once - I think.
