wrong direction

Film International Herald Tribune reports of the Japanese remake of one of my favourite films, Sideways:

"The two male characters (Michio and Daisuke instead of Miles and Jack) now head from Los Angeles to Napa Valley, instead of traipsing up to Santa Barbara. While wine sales are on the rise in Japan — thanks in part to the comic-book sensation "Kami no Shizuku," or "The Drops of God," about a heroic odyssey to find the best wines in the world — a lesser-known wine region like Santa Barbara would still resonate little with audiences. And heading to Napa allowed the filmmakers to weave in some local landmarks. "You can't do a road trip in California without going over the Golden Gate Bridge," said Cellin Gluck, the new film's director."

I wonder if an even more interesting approach would have been to make one of the characters -- the one who's a wine buff -- a fan of the original film and have them go off and try and recreate the same trip but they end up going in the wrong direction.
