Walk Hard: The Dewey Cox Story, released in 2007, probably should have ended all musical biopics. It’s a ruthless satire of then-recent hits Walk the Line and Ray that exposes every clich&e and tired trope of the genre.

And yet, Hollywood keeps churning them out. In just the past few years we’ve seen movies about Elvis, Bob Marley, Robbie Williams, Amy Winehouse, Bob Dylan, and Bruce Springsteen.

Some manage to steer clear of the landmines better than others, but they all summon the ghost of Dewey Cox to some degree. I can’t watch a musical biopic flashback without hearing the phrase “Dewey cox has to think about his whole life before he plays.”

Dewey is played winningly by John C. Reilly, whose Oscar-nominated turn in the 2002 musical Chicago suggested he had the vocal chops to tackle this material.

Today’s song, ‘Walk Hard,’ is Dewey Cox’s first single. He plays it to win over a skeptical music exec and it becomes a radio hit 35 minutes after its release, sparking Dewey’s rise to fame and all the problems that come with it.
