Jean-Paul Belmondo film, not later than 60s--70s. In one sequence, he's in a card game in a little club, runs out of cigarettes, walks out to a hard-top, folds-into-the-trunk convertible (remember?), Ford I think, unlocks it, puts the top down, drives straight ahead one block to a store, stops, puts top up, goes in and buys cigarettes, comes out, puts top down, backs up the same block, puts top up, returns to game. I've ransacked imdb without success. (Black and white crime comedy as I recall, probably subtitled.) Thanks for any clue.
