Trivia: This was filmed in only two days.
Trivia: In the film, Pollyanna shows Reverend Ford (when he practices his fired up sermon in the field) the locket with the quotation "When you look for the bad in mankind expecting to find it, you surely will," inscribed upon it and then credits the adage to Abraham Lincoln. Seeing an opportunity, Roy Disney, Walt's brother and Disney Studio CEO, had thousands of promotional lockets with those inscribed words (duplicates of Pollyanna's charm bracelet as well) produced and sent to gift shops. By a stroke of luck, while on a family trip to Disneyland, the screenwriter/director, David Swift, happened to notice the locket copies in one of the Disney gift shops and contacted Roy at the Disney Studio and told him to recall all the lockets straight away, because he deliberately fabricated the quote for the film - Abraham Lincoln never said it.
Trivia: When Charles Hawtrey gets out of bed and steps in his chamber pot it starts rolling around on the floor and he tells it to be quiet. He was not meant to say it, he just improvised.
Trivia: The Christmas party was really filmed just before Christmas, with almost all of it filmed in the first take as everyone was in the holiday spirit already. Director Billy Wilder said "I wish it were always this easy. Today, I can just shout 'action' and stand back."
Trivia: In the opening title card, you will notice there is no "Story" credit. Michael Maltese was the story writer, but as he had left Warner Brothers for Hanna-Barbera, his name was removed from the credits.
Trivia: Final Warner Brothers cartoon in which Arthur Q. Bryan voiced Elmer Fudd. The voice actor died in November 1959.
