Although his most frequent on-screen billing has been Charlie Robinson, Night Court had credited him as Charles Robinson throughout his 1984–1992 stint as Mac. In two of his earliest film appearances, 1974's Sugar Hill and 1975's The Black Gestapo, he was credited as Charles P. Robinson. Some of his credits have been occasionally commingled with those of Charles Knox Robinson who, billed as Charles Robinson, was featured in numerous films and TV episodes between 1958 and 1971.
