Most of My Old Lady is set in the kind of apartment you have dreams about after eating Camembert late in the evening: old, rambling, with a garden view through big upper-floor windows in the back. And, oh yes, it’s in Paris. The film is based on a play by Israel Horovitz, and no wonder Horovitz (making his feature-film directing debut—at age 75) chose not to open up the stage work; that’s one great pad. There are shots of characters strolling along the Seine to Mark Orton’s wistful accordion music, but mostly we’re indoors. The apartment is at the heart of the story, anyway.
