Last weekend I had some time to myself, so I pulled out my Criterion Collection Confessions of a Shopaholic and sat back for some good ol' cinema and social commentary. Among its many merits, the high point of that movie, in my opinion, has traditionally been where the Isla Fisher character gets in a catfight with another shopper over a pair of gaudy Gucci boots at a super designer warehouse sale. It was movie magic until the seventh viewing, when my keen eye detected that her opponent was a good head taller, and couldn't possibly have worn the same size shoe! For some time I fretted that P.J. Hogan, one of the great auteurs of our time, had made an obvious blunder, sacrificing continuity for a cheap site gag. But as I pondered, it became apparent just how truly brilliant this moment was!
