CANCELLED: Steven Spielberg, 54, has withdrawn from his planned participation in next month's Venice, Italy, and Deauville, France, Film Festivals, reports Variety. The filmmaker was due to screen his "A.I., Artificial Intelligence," which was released in the U.S. earlier this summer. (The film was deemed a domestic box-office dud.) Spielberg is reportedly citing post-production delays on his upcoming $80 million movie starring Tom Cruise, "Minority Report." "A.I." stars Haley Joel Osment and Jude Law are expected to fill in for Spielberg at both festivals . . . AILING: MGM's great swimming star, Esther Williams, 80, took a spill down the stairs of her Beverly Hills home last May, reports Variety columnist Army Archerd. She fractured an ankle, which then became dangerously infected from the metal plates inserted to support the joint. Hospitalized for a month, the former swimsuit model, whose '50s movies include "Dangerous When Wet," is only now getting about with a walker, says Archerd . . . BORN: Judy Gold, host of HBO's "At the Multiplex With Judy Gold," gave birth last Thursday to 7-pound, 8-ounce Benjamin Dov Callahan-Gold at Lenox Hill Hospital in New York City, her publicist says. The TV personality and her partner, Sharon Callahan, also have a 4-year-old son, Henry.
