Despite setting their sitcom in a Pittsburgh suburb, the creators of Mr. Belvedere had never actually been there. They used a calendar provided by the Pittsburgh Chamber of Commerce to base their scripts on.
Nine episodes of the show never appeared on ABC and only showed up in syndication- the final two episodes of the fifth season and seven episodes of the sixth season. While no reason was given for why ABC chose not to air the two episodes from the fifth season, the seven sixth season episodes were never aired due to poor ratings. ABC never chose to burn those episodes off in the summer, as is frequently done in these situations, but it did burn off the last two episodes as a two part series finale during the summer of 1990.
