But you know, so what? Here's a movie destined for cult status. Sure the jokes are hit and miss. But when it does hit, it strikes like a daisy-cutter, often in the form of a perfectly delivered line. Like The Big Lebowski, Office Space, Anchorman and other comedies that found their audience on home video, the "Judd Apatow Presents" Walk Hard bursts with quotable dialogue, which is the most important ingredient for a comedy to gain a cult following. Plus, the film's original music is catchy as hell. So that's two arguments for converting folks into believers.

The third argument is John C. Reilly who plays Dewey Cox, a composite of just about every iconic American music figure over the last 40 years—although the character definitely owes most to the Johnny Cash image. Reilly commits to Cox with such enthusiasm that it reverberates through every scene of the movie. It's contagious. And you can't help but enjoy the film even during the flatter bits.

Yet, unlike most flicks that go on and gain a cult following, no one has to wait for a decent DVD here. Walk Hard's 2-disc edition is stacked. We get the usual deleted scenes and an amusing audio commentary with director Jake Kasdan, Apatow, Reilly and executive producer Lew Morton. Featurettes include an interesting look at the film's solid music (which was wrongfully snubbed by the Oscars) and a surprisingly humorous "making of" doc. There are also several mockumentaries, treating Cox as a real person and exhausting every Cox=cock pun imaginable (although look out for Sheryl Crow and how much she revels in the "I love Cox" jokes—good stuff).

For those of us who dig the music, the DVD delivers original song demos from several different musicians and uncut performances of 8 tunes from the movie. One would expect an outtake reel to be a logical extra for a film like this. Yet, it's the most notable M.I.A. extra on the disc. Although sort of making up for it is a funny bonus feature called "Line-O-Rama" that shows several different ad-libs. But it's short and doesn't feel like a real outtake reel.

The best feature is the choice between the film's theatrical version and "American Cox: The Unbearably Long, Self-Indulgent Director's Cut," which contains 25 extra minutes (which is actually more hit than miss). My preference swings towards "America Cox." It's funnier and, despite the longer running time, better paced than the theatrical cut. Or maybe it just felt quicker because I watched it in my living room and hit pause a lot.

Regardless, the director's cut contains the Patrick Duffy beat-down—which was absent in the original version despite being a highlight in the trailer. And watching Duffy taking a face full of Cox fist is worth the price of purchase alone.
