Revealing mistake: When Frasier comes into the chalet after skiing he doesn't show any of the visible effects after a hard day on the slopes. Meaning, his face isn't even flushed from the cold, his hair is perfectly combed after wearing a hat and there is not even a drop of snow on his boots.
Revealing mistake: When the coward is being branded using a red hot poker, you can see that the metal 'C' hasn't been heated at all when it is brought next to his face. Compare it to when they tested it on a piece of wood beforehand. The poker is also covered in a really fake-looking red paint. (02:02:55)
