Dean Martin and Jean-Paul Belmondo

Just wanted to see those two names together. Watched the original "Breathless" and wondered whether that character's fate might foreshadow my own? They are also connected through Jean Seberg, who co-starred in both "Breathless" with Jean-Paul and 1970's "Airport" with Dean Martin. The latter was Seberg's final major film. Some years later she committed suicide.
