Wahoo Moments

Many movie versions of books have what I call wahoo moments. In last year's Narnia, for example, when the hilt of the sword and then the kids rise out of the river. Or, any number of times in Harry Potter. My favorites are when Harry rides Buckbeak in Prisoner of Azkaban and when he reappears on his broom during the First Task in Goblet of Fire. Of course, when Mr. Darcy shows up in the early morning in the newest version of Pride and Prejudice. What other wahoo moments are out there?
