Judd Apatow, after years of being a Hollywood underdog with many failed series and movies and a cult following, is now relentlessly assaulting the box office. First it was 40-year Old Virgin, then Knocked Up, and Superbad which is, as I type, undoubtedly printing money. And now he's released a trailer for his next conquest, Walk Hard. I personally miss the bittersweetness of his ill-fated show Freaks and Geeks over the broad comedies, but he's still making broad comedies better than anyone. And this spoof of musician biopics just might be his funniest yet.
