As busy as Darren Criss is, he still has time to get back to his roots. Star Kid Cast is planning A Very Potter Threequel, much to fans delight!
When asked about a third musical at San Diego Comic-Con one month ago, Joey Richter told fans that they had an “amazing” script but were waiting to see if Darren Criss would be available for it.[Source]
In the past month it seems Criss was able to find time in between Glee and How To Succeed to reunite with the StarKid cast.
