Co-written by and starring "Glee" star Darren Criss as the boy wizard, the (unauthorized) musical version of Harry Potter was created by StarKid Productions, a group of college students originally from the University of Michigan that included Criss. The show was staged on the school's campus in 2009 and became a sensation after video of the show was uploaded to YouTube. Songs include "Gotta Get Back to Hogwarts" and "Granger Danger." A sequel was also performed.
