WOODY Allen fans, rejoice! "Vicky Cristina Barcelona," which opens tomorrow, is the Wood Man's funniest film in decades. At least that was the consensus in Southampton the other night, where the movie - starring Javier Bardem as a sex-obsessed painter in a love quadran gle with Scarlett Johannson, Rebecca Hall and Penelope Cruz - was screened for the likes of Joy Behar, Lorraine Bracco, Calvin Klein, Donna Karan, Alfie Fanjul, Pete Peter son, Sandy Hill Pittman, Marjorie Gubelmann, Debbie and Leon Black, and Tory Burch and Lyor Cohen. Afterwards at Tus can House, as Robert Wilson and Judy and Al Taubman dined, publisher Jason Binn was joined by Verne Troyer, the minuscule Mini-Me of the "Austin Powers" films, who sat on a couple of phone books.
