First two movies directed by Guy Ritchie and starred Robert Downey Jr. as genius detective Sherlock Holmes and Jude Law as his trusted apprentice John Watson were blockbuster hits. Especially with its action-based approach, the series got lots of good reviews and feedbacks from fans and critiques.
After the success of the first two movies, plans for the third one also has started by production team and in 2011, Sherlock Holmes 3 was announced. However, the project did not continue efficiently and couldn't move beyond the screen-writing process despite the positive attitude of cast and crew towards the third movie. Finally in 2018, Sherlock Holmes 3 had a release date by Warner Bros, which is December 2020. Yet later on the project delayed one entire year to December 2021.
As the production process goes on, HN Entertainment leaked a rumor about the new movie. According to an unknown source, Sherlock Holmes 3 will be set in Old-West era San Francisco. Thus, it seems the British detective partners are going to have a trip to the USA to solve another mystery.
