Young Frankenstein, officially known as The New Mel Brooks Musical: Young Frankenstein, is based on the 1974 film of the same name (written by Mel Brooks and Gene Wilder). It’s a parody of the horror film genre, especially the 1931 movie Frankenstein and its 1939 sequel, Son of Frankenstein.
The musical opened on Broadway in November 2007 and closed in January 2009 after 484 performances. The show featured Brian D’Arcy James, Sutton Foster, Megan Mullally, and Kristin Chenoweth (I know, she’s everywhere!).
