The Fox network, which has been aiming to bring back the family-comedy-with-a-twist genre of TV series, is developing "The New McToms," a hybrid multi- and single-camera half-hour executive produced by Salma Hayek. Fox has a track record of success with that sort of show, having scored with the multicamera "Married ... With Children" and single-camera "Malcolm In the Middle." Written by Boyce Bugliari and Jamie McLaughlin, "McToms" centers on a conservative matriarch who must face the reality of her three children's ethnically diverse marriages.ABC Studios, where Hayek's Ventanarosa has an overall deal, is producing the project.
