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.
