I wonder why, during filming of the colour "Saint" shows, they used the same streets over and over again that were obviously constructed in the studios just for this purpose. Depending on which country the stories were set, all they did was to change signs in the streets to Italian, German, French etc. but the locations were instantly recognisable.
Do you think this was done to cut costs, or to enable that scenes were shot without possible interruption from watching crowds?
