Fred Willard was originally cast as George Winger. During rehearsals, Willard realized that the producers had mistaken him for Frank Bonner and that he was cast accidentally. Willard was fired after the original pilot.

Chad Lowe, who played the title character, quit the series after five episodes due to a contract dispute and creative differences. His role was recast with Rossie Harris and production resumed under the new title "Under One Roof".
