London, Ontario is significant to Sherlock Holmes (2009) because it is the birthplace of Rachel McAdams who stars as Irene Adler in the film adaptation. Although she grew up in St. Thomas, her connection to Ontario involved acting in kids theater companies when she was young finding her passion. This background adds a personal connection to the map by showing where the actress behind the character began her acting journey.
I found this information from the Canadian Encyclopedia, an online academic article. This source would be an example of platforms as gatekeepers because the editors decide what information is posted and how its presented to the viewers. This website helps me trust the information, but also helps me see that we as readers only receive a certain amount of information on actors and people’s lives in general. Mapping Rachel McAdams birthplace on Cove helps me to gather a better understanding of the characters and production of the film. Rather than simply talking about something the encyclopedia keeps from viewers, my map highlights a connection that allows me to share my interpretation with a community.
