Pirates of the Caribbean (The Curse of the Black Pearl) - Hat Goes on, Hat Goes Off!
Alright, start the movie, and watch for a long time.
You're watching for the part where the two idiot zombies come out of the cave in dresses and parasols.
One of the zombies eventually shoots off the Commodore's hat. In the VERY NEXT camera cut it's back on again.
What do you think?
A keen eye, but of course the movie itself.
