YMMV: A Knight's Tale
Big Lipped Alligator Moment: Adhemar's hallucination just prior to his defeat at the end is so bizarre and out of nowhere that it's actually cut out on many TV airings of the film.
Nearly every bad thing that has happened to Adhemar in this movie has been at least an indirect result of Prince Edward — or more accurately, Adhemar's own refusal to joust him. A short time after this occurs, Adhemar is called away to war — on the Black Prince's orders — where he frequently sees the results of the tournaments that have taken place in his absence, all of them being won by William and the fact of it all causing him great anger. Then, when he comes back, he manages to expose 'Ulrich von Lichtenstein' as William Thatcher; Edward's retaliation is to fully pardon and knight William, urge him to fight in the tournament and then cheer him on.
