27. Down the Garbage Chute ('A New Hope')
After Han Solo (Harrison Ford), Luke and Chewbacca (Peter Mayhew) bumble their way into a fierce firefight while breaking Princess Leia (Carrie Fisher) out of an Imperial prison block, they need an exit strategy — so Leia takes charge and sends them down the garbage chute. Note to self: This is not a good escape plan, unless someone likes being dragged under by a tentacled monstrosity in a lake of filth. And should you have forgotten that Lucas took inspiration from the old Flash Gordon serials he loved growing up, he puts the crew in a classic cliffhanger situation by literally having the walls close in on them.
