Lynne Littman's Academy Award-winning "Number Our Days" looks at a community of elderly Jews in southern California. They might not have much, but they have each other. One scene mentions that a number of apartment buildings have gotten demolished and replaced with other things. And this was in 1976! Think how bad it's gotten since then!
Anyway, it's a good look at what is almost certainly a disappeared community. It ranges from humorous to bittersweet. Lynne Littman has directed a handful of works since then, while Barbara Myerhoff died of lung cancer in 1985.
