Walk Hard: The Dewey Cox Story has 20-20 hyperbole.

For 45 minutes, it zings along on perfectly pitched overstatement. It gleefully puts elements of the Ray Charles of Ray and the Johnny Cash of Walk the Line into the story of rock star Dewey Cox (cue drum roll) ... a boy who could never please his father even after he became a man ... and a man who created classic rock even without a sense of smell.

Walk Hard: The Dewey Cox Story (Columbia Pictures) Starring John C. Reilly, Jenna Fischer, Tim Meadows. Rated R. Time 92 minutes.
