Judd Apatow-produced films usually don't need much marketing help.

Walk Hard: The Dewey Cox Story," Columbia Pictures is launching a novel tie-in for the unconventional comedy. Star John C. Reilly will tour the country in character as Dewey Cox, the fictional rock 'n' roll icon whose music influenced a nation. Reilly will perform live as Cox with his band, the Hard Walkers, for the "Cox Across America Tour."
