If you ever find yourself playing “Six Degrees of Joan Cusack” (which is not actually a game but should be—no disrespect to Kevin Bacon), you can use either High Fidelity or School of Rock to get to Jack Black. School is clearly Mr. Black’s movie, but Ms. Cusack steals this scene by declaring her devotion to the great Stevie Nicks. Watch Joan’s face as she recognizes what song is coming out of the jukebox. That, dear readers, is what great acting looks like.
