 MISC: In the closing credits, "It Happened One Christmas" carries a  1978 copyright date, although the film originally aired on Sunday,  December 11, 1977. The notice reads: "Copyright (C) MCMLXXVIII by  Universal City Studios, Inc. All Rights Reserved;" whoever printed  the titles unknowingly inserted one "I" too many. It should have  read MCMLXXVII, for 1977.
