D: Eric Appel.
S: Daniel Radcliffe, Evan Rachel Wood, Rainn Wilson, Arturo Castro, Julianne Nicholson, Will Forte, Lin-Manuel Miranda, Toby Huss, Weird Al Yankovic, Spencer Treat Clark, Patton Oswalt, Jorma Taccone, Michael McKean, David Dastmalchian, Conan O'Brien, Jack Black.
A hilarious comedy biopic spoof, skewering in particular the slew of movie music biogs. Wall-to-wall cameos. It has the relentless energy of an action movie.
