Her film work didn't begin until 1978, when she played a small part in the Chevy Chase film, Foul Play. From there she showed up in a lot of smaller roles on television and the movies, usually as older women. She can be seen in old Happy Days episodes as Fonzie's Grandmother.
Her most interesting work, though, was with David Lynch, with memorable scenes in Blue Velvet, Wild at Heart, Twin Peaks, and the Twin Peaks spin off movie Fire Walk with Me. In those, she proved that she was just not an older face, but a pretty good actress as well.
Francis Bay passed away on September 15, 2011. And although her name isn't well known, when her characters show up on the screen, her presence is long remembered, making her today's pick for Not Very Famous...but should be.
