Character mistake: In the scene where Kris's knowledge is being tested, he incorrectly gives the vice president of President John Quincy Adams. Kris states John Quincy Adams' vice president was Daniel D. Thompkins. That's wrong. John Quincy Adams' vice president was John C. Calhoun. Daniel D. Thompkins was the vice president under President James Monroe.
Character mistake: In the final sermon, Henry says "Uncle Henry" instead of Uncle Harry - as shown in the earlier typed sermon.
Character mistake: Tenango is a destination/rendezvous town, but at the luncheon a character refers to it as Durango.
