 Hand-held video cameras allowed the actors to move from within the building directly onto the street - Something that was just not possible with traditional studio-based production and created a new degree of realism for the viewer.Many of the crew enjoyed the autonomy of working at Thames' East London outpost, however transport links to the area were then very poor and many of the Teddington-based staff disliked the cross-city journey from West London.This remained a constant at Artichoke Hill, and may have been a factor in the choice of a West-London location when the filming base was forced to move for Series 3.
