Did you know that the Christmas scenes from the 1974 movie and the episode “An Unforgettable Christmas” from the eighth season are actually an adaptation of the chapter “Mr. Edwards Meets Santa Claus” from the book Little House on the Prairie, written by Laura Ingalls Wilder?
Fans of the original books know that a lot changed when creating the television series.
However, this Christmas story from the book was faithfully recreated in the pilot movie and then included in this episode of Christmas Memories.
