Sure it helps to have a working knowledge of the biopic genre to fully appreciate just how funny Walk Hard: The Dewey Cox Story really is, but even a lack of familiarity with those movies won't matter. Walk Hard is a truly inspired and sensationally funny and clever musical send-up that is a good bet to become the comedy smash of the holiday season. Cowriter/producer Judd Apatow has pulled off the movie comedy equivalent of the Triple Crown. John C. Reilly, already a Best Actor Golden Globe nominee for this, is fantastic as a backwoods singer who rises to fame in the '60s and '70s, becoming a legend in the process, sleeping with hundreds of women, marrying a few, fathering boatloads of kids, and living the glory and hard life of a superstar. His songs were apparently as influential as the Beatles, a group Dewey hangs out with in a spiritual quest to India. The sequence with Justin Long, Paul Rudd, Jason Schwartzman, and Jack Black is a riot, especially watching Black becoming Paul McCartney and battling Rudd's dead-on John Lennon. Of course, just as in the Johnny Cash biopic Walk the Line, this film works overtime to satirize, Dewey finally finds true love in the woman (Jenna Fischer) he wants to "Duet" with for the rest of his life. With over 30 very clever, somewhat raunchy songs to perform, Reilly proves he is not only a gifted comic but a really good singer as well. He will have you laughing from start to finish. And if the film is sometimes too smug and impressed with its own jokes (we lost count of all the gags built around Dewey's last name), more times than not it scores with the now-patented brand of Apatow humor and even a little heart.
