A screen-location claim needs a named, reviewable source. Official studio, rights-holder, public-authority and tourism sources are preferred. Named independent research may be used when it is the clearest available account; if a precise pin remains doubtful, the page says so once in plain English.
Story settings, fan-favourite alleys, production-design venues and the Palace Theatre can all be enjoyable, but they are labelled for what they are. The site does not convert resemblance or repetition on other websites into filming fact. Each location also explains its real visitor context: public street, working station, market, residence, diplomatic building or ticketed venue.
Walking times and route sequences are planning estimates assembled from mapped geography and official transport information. They are not live journey predictions or on-street access audits. Check TfL’s live journey planner for the day and the relevant venue for current entrance and access arrangements.
