The Aviator's Wife, 1981 - ★★★★
Yet another in our Eric Rohmer fest. I think this might be my favourite of them so far. A guy follows a couple around Paris because the man is the (married) ex of his girlfriend, and he wants to know what the man — presumed to be the titular flier — is doing with the woman he's with (is she the titular spouse?), when he's supposed to have left the city.
Daft but fun, as usual.
