The much-anticipated fourth installment of the Matrix franchise appears to be scheduled do some shooting in San Francisco early next year — though it's not clear where.

News has been dribbling out about The Matrix 4 — which likely won't be called that — ever since Keanu Reeves and Carrie Ann moss were confirmed to be part of the project back in August. Original co-creator Lana Wachowski is on board as director, with the script being written by Wachowski along with Aleksandar Hemon and David Mitchell. (Mitchell wrote the novel Cloud Atlas, which the Wachowskis adapted into a 2012 film.) And we recently learned that actors Neil Patrick Harris and Jonathan Groff are part of the cast. But now, as SFGate reports via some internet chatter, San Francisco is almost positively on the list of shooting locales for the fourth Matrix film.

The San Francisco Film Commission has a "major" film with the working title "Project Ice Cream" on the books and set to shoot in the city in February. And Production Weekly, a trade publication, has that working title listed beside The Matrix 4. So it seems that cat is out of the bag.

This would not be the first time that Lana Wachowski chose to come to the Bay Area for a shoot. Most recently, she was here for multiple shoots in 2014 and the spring of 2016 for the Netflix series Sense 8. And The Matrix Reloaded had car chase sequences that were shot in Oakland and Alameda, as well as a much reviled rave scene that was shot in an old Naval Air Base hangar in Alameda.

Wachowski developed and produced the first three Matrix films with her sister, Lilly Wachowski. Both underwent gender transitions in the last decade, and Lilly Wachowski has taken time off from film and TV production since her transition several years ago. Lana proceeded to work on Sense 8 without her, and she appears to be flying solo on the new Matrix movie as well.

The Matrix Reloaded and The Matrix Revolutions were shot simultaneously and both released in 2003. As Forbes reported in August, star Keanu Reeves' comeback success with the John Wick franchise appears to have revived interest at Warner Bros. in making another installment of The Matrix happen.
