When Santa Claus decides not to visit a small town due to a letter written in a local newspaper, it’s up to Joshua Trundle, the local clockmaker to come up with an idea to make amends. But when his idea of a giant singing clock goes awry, it may be up to Albert, the little mouse that wrote the insulting letter to fix the situation. Here are a few movie mistakes to look for in the animated classic “Twas the Night Before Christmas”.

• At the very beginning, the overhead view of the Trundle’s sitting room shows yellow and purple stockings hung over the fireplace with the purple one at the end of the hook, and the yellow one closest to the wall of the fireplace. But later, when Mr. Trundle is shown hanging them, it’s the purple one that’s closest to the wall. When Santa comes down the chimney, it’s a purple and white one hanging with the white one closest to the fireplace. The stockings are gold and purple a few moments later when Santa is filling them, with the purple one closest to the fireplace.

• Father Mouse is first shown reading in bed. To his right, the back of Mama Mouse’s head can be seen on her pillow. But in the overhead view, when he gets out of bed, there’s nothing on the pillow. (Although there is a lump under the covers.) Later in the story, it’s back to the same scene again, Father Mouse blows out the candle and gets into the bed and Mama Mouse’s head is on the pillow.

• When the family confronts Albert, he’s sitting at his desk and the book in front of him is purple. When it cuts to a close-up of Albert, the book is red. Also during this scene, when Mama Mouse tells him to write another letter, the bookshelf behind her has five books on the top shelf, all slanted against the right. When Father Mouse starts to sing, there are seven books on the shelf and two are on the left.

• When Father Mouse is showing Albert that grown-ups care about Santa too, he takes him to Joshua Trundle’s workshop. When they’re walking across the top of his work station, the ornate clock at the bottom has its long/minute hand pointing to the twelve. When they bounce onto the workbench, the same clock’s long/minute hand is on the two.

• When Santa lands in the Trundle’s fireplace, his cheeks and nose aren’t rosy like they had been. They’re rosy again when he puts his pipe in his mouth.
