Pic will begin shooting in New York on Sept. 19.

Hudson recently completed work on the drama "Winged Creatures."

Kim Cattrall, Kristin Davis, Cynthia Nixon and Chris Noth have signed to reprise their roles, and Michael Patrick King, skein's longtime creative leader and exec producer, is set to write and direct.

The film will be produced by King with Parker, John Melfi and Darren Star, who created the series, based on autobiographical columns penned by Candace Bushnell.
