Initially unable to raise the $3 million budget for Whiplash, Damien Chazelle made a proof of concept, 18-minute short film that premiered at the 2013 Sundance Film Festival. Now available online, the short looks to be more or less an exact excerpt of the feature script, distilling Fletcher’s emotional manipulation, rage, and abuse into three consecutive scenes. The precise editing, gliding camerawork, and J.K. Simmons’ high octane performance are all on display, though the short — presumably for budgetary reasons — lacks the isolated, brooding mood and dark yellow color pallet of the feature version. Also notable is that Johnny Simmons was originally cast in the Andrew Neyman role; safe to say, Chazelle upgraded on that front.
