Whiplash is the name of a tune that a student at a prestigious Manhattan music school must master. Andrew, played by Miles Teller, is a jazz drummer who dreams of one day being, ‘one of the greats.’ Pushing him toward that goal is a teacher named Terrance Fletcher, played by J.K Simmons. If Voldemort decided to get a teaching gig, he would be Fletcher. Fletcher is, in equal parts, charismatic and monstrous. He hurls chairs at students, slaps them, decimates them with singularly unique insults and plays them against each other in perverse and sadistic ways.
