Walk Hard, a parody of the biopic genre, features Reilly as a fictional musician named Dewey Cox, and Jenna Fischer as his backup singer and wife, Darlene. The story follows Dewey as he eventually gets caught up in the fame of rock 'n' roll: he sleeps with 411 women, marries three times, has 22 kids, 14 step kids, and gets addicted to � and kicks � every drug known to man. Jake Kasdan directed the movie, and Kasdan and Judd Apatow were co-writers.

The Walk Hard soundtrack CD, due to hit the streets on December 4 on Columbia Records, leads off with Crenshaw's title tune and includes compositions by such writers as Dan Bern, Charlie Wadhams, Michael Andrews and Mike Viola. Soundtrack producers were Manish Raval and Tom Wolfe.
