While Bloomfield wants to be the next Sundance, Montclair currently has bragging rights as the suburb of choice for Madison Avenue. All those lighting trucks, dressing rooms and film crews several readers spotted yesterday at Grove and Watchung were busy filming a commercial for Pizza Hut. A bit ironic that the massed produced pizza corp would choose a location in Baristaville, where we√¢‚Ç¨‚Ñ¢ve got plenty of yummy mom and pop places to choose from. Other filming yesterday: a commercial for Cingular, produced by Park Pictures, was shot at Haddon Place and South Mountain. Over on Alexander as well as Norman Road, stills were being shot for a non-smoking campaign.
