Okay so the Count, the Swedish Chef, and Dr. Bunsen Honeydew & Beaker are all very good contenders for Potions Professor in a Muppet adaptation of Harry Potter, but my brother and I have concluded that the best, the absolute best version of this is to have Snape be one of the human characters. So we can have him standing there attempting to look dignified while surrounded by rambunctious muppet students, and having serious conversations with Professor McGonagall (who is a muppet cat in a witch’s hat and glasses who sometimes turns into a real cat). There might be multiple Potions Professors but Snape is human.

And he’s played by Daniel Radcliffe.
