5. 'Young Frankenstein'
After spoofing Westerns with 1974's Blazing Saddles, Mel Brooks decided to mock monster movies with Young Frankenstein. Gene Wilder plays the grandson of Dr. Frankenstein, who travels to Transylvania after inheriting his father's estate. He's ashamed of his family's legacy, but quickly gets pulled into the madness when the monster is set free. It was turned into a Broadway musical in 2007 and ran a little over a year.
