Stanley Dock is significant to Sherlock Holmes (2009) because these locations were used as "real-world filming locations." It added the action and effect that it came to life during scenes filmed here. The film would not have been as extreme as it was, if it were filmed at a fake dock. The docks were a popular location during this film because a lot of action happened there, which added excitement for the audience. These two docks were also important because they had been connected to the shipping industry and the transportation of commodities in London. They played a key role in revealing the extent to which the port facilities in London were utilized for commercial purposes. I found this information on wikipedia. This source is an example of low barriers to entry because anyone can add their own personal information and opinions on this source. Mapping this location on COVE adds a grassroots layer because it helps the audience connect real world places to locations in a film.
