When Don and Barbara Rickles met Bob and Ginnie Newhart, they became friends for life — as told in Judd Apatow’s latest film

This movie, codirected by Michael Bonfiglio, is titled “Bob and Don: A Love Story.” It is only 20 minutes long and playing not in theaters or on any streaming service. But it is on The New Yorker magazine’s website, accompanied by a fine story by Bruce Handy.
