The Elf Who Saved Christmas (1993)

After receiving no letters by Christmas Eve, Santa calls the elves together and announces that no one believes in the spirit of Christmas anymore and he plans to retire. Toby, the tiny mailroom elf, sets out to find the letters and tumbles through the mailbox into the den of the wicked Mrs. Buzzard (Jo Anne Worley), who has put a spell on the mailbox to ruin Christmas.
