Don't know it it has made the list yet, but don't forget NORMAN, IS THAT YOU? You can still catch it on late, late, late cable. Story is about a black man bringing home his white lover to his parents' home. Redd Fox plays the father. The cable station I saw it on was advertising it as a 70s/80s version of GUESS WHO'S COMING TO DINER. You be the judge. Don't forget SHOWBOAT there is the interracial subplot in that one.
