I was not aware Andrew could sing, but he's an amazing actor. I would love a p.o.c. to play Michael, Brandon Victor Dixon comes to mind. Emma Stone would be a pretty amazing Susan, they will definitely cast a known actress for this.
Even if Ben Platt was a Michael (he's really not), he could never be cast alongside Andrew Garfield. Big casting mismatch when they're supposed to be school friends.
according to deadline Vanessa Hudgens has been added to the cast. Not sure what role she was cast in, as Alexandra Shipp was cast as Susan. Not too sure about Hudgens being added. thoughts?
