I can’t count the number of times I’ve been watching some Square TV and found myself pointing at a passing profile or crouching body, shouting “Hey! That’s Saperstein!” (If anyone remembers Russell at all, it will be for his performance as wallpaper of that name on Kojak.) This man had no lines, no visible professional life, no notable character. And yet he was a frequent piece of set dressing whose uncredited appearances at least equaled, if not outnumbered, his listed credits. He was the ultimate backlot actor… seemingly indistinguishable from the grey painted plaster of the sets in which he was installed.
