Glee star and Broadway veteran Darren Criss recently reunited with his Team StarKid pals to celebrate all things Harry Potter at Chicago's LeakyCon. Criss and co. attended the Harry Potter convention in order to present A Very Potter 3D: A Very Potter Senior Year, the third installment in their series of Harry Potter musical parodies. Criss and his collaborators first rose to YouTube fame in 2009 when A Very Harry Potter Musical hit the web. A Very Potter Sequel followed the next year. A third series was in the works, however was never completed and staged due to Criss' busy schedule once he became a TV superstar. Luckily for Darren fans the wait is over! The whole video of A Very Potter 3D isn't available yet, but until its release check out Criss as he gets back into his wizarding robes in rehearsal!
