Camden Council has agreed to trial the removal of cars from part of the street which is popular among tourists as well as celebrities but often sees pedestrians spilling over onto the pavement.
Roberta Michels-Hopkins, from Camden, New Jersey, disappeared without a trace in 1981 after she reportedly went to the shop to buy a pack of cigarettes and never returned.
Shooting was taking place on Monday at the Ackland Burghley school in Tufnell Park and filmmakers were given permission to suspend three separate parking bays across two roads.
