If you loved Antoine et Colette, try L'Amour en fuite
Un pont entre un film que tu as déjà vu et un que peu de gens ont croisé. Voici ce qu'ils partagent, et ce que le second fait que le premier ne fait pas.
Ce qu'ils partagent
Both films are directed by François Truffaut, and they both carry the bittersweet, tender mood tags, and they sit in Comedy / Drama / Romance territory. If that's the register that drew you to Antoine et Colette, the second film will land in a comparable space — through a different lens.

What L'Amour en fuite is
A sequel to an old romance where two exes reunite via a book deal, naturally. Antoine Doinel, still stuck in his thirties, peddles paperbacks and romantic nostalgia. Their intellectual kibitzing somehow passes for passion.
