Knowing another language means you can watch artsy french movies without the sub-titles.
Last night I watched the Gainsbourg movie, if you like Parisian extravagance (smoking, sex, smoking, witty sexy woman, smoking and more smoking) then you might like this movie. The french do it way better, everything. I mean if your country produces the best pastries and the best looking woman you are doing something right.
What gets me about this movie is how Gainsbourg uses his charm and talent to get woman, who cares if you could hang your jacket off his nose.
