Europeans trying to act like 1950's Americans is always amusing.
Looking for the U.S. market, they kitsch it up into bad-good goofiness.
The lack of contractions ("is not" instead of "isn't", etc.) in the dubbing is nifty too.
Making the dialogue sound like something in an "ancient Roman" flick, except it 's set in Jean Paul Belmondo's locale, instead.
Euro-corn sci-fi for their non-existent Continental drive-in movies.
The lines are loopily incongruous, too:
"Let's both stay home, with our records!"
and:
"You seemed to be performing some sacred ritual."
(Camus would have laughed and laughed!)
