In the beginning as Buz and Tod are walking along the sidewalk, you can see people on the sidewalk across the street facing them to watch the filming. You see several who have gotten to their sidewalk who watch them as they walk by. Also some of the stores have people in the doorways watching Tod and Buz walk by.
Three guest stars would have shows of their own: Darren McGavin in Kolchek (and was doing Riverboat); Ed Asner in Mary Tyler Moore, and Al Lewis, The Munsters.
George Maharis would play a boxer in Rich Man Poor Man, and ironically, as he's here dealing with a once-great boxer, he'd play a great boxer who gets beaten-up by has-been boxer Nick Nolte.
