We’re still over a year from the arrival of The Matrix 4, but San Francisco residents were treated to an early preview this week, as Keanu Reeves and Carrie-Anne Moss were spotted filming in the city.

In a video shared on Twitter, Reeves and Moss can be seen reprising their roles as Neo and Trinity as they ‘ride’ on a motorbike in – you guessed it – long black coats. The soundless video also stars a number of crew members, none of whom seem to actually be filming anything, which makes sense given another clip sees Reeves interacting with passers-by.

Other videos shared on the platform show more high-production filming, including countless extras all dressed in black, atmosphere-setting smoke, and Moss actually driving the motorbike with Reeves standing up behind her. The pair are also seen jumping off a building. Very chill, very normal things to see as you stroll through San Fran.

The fourth chapter of the sci-fi franchise was confirmed in August last year, with Lana and Lilly Wachowski returning to direct, as well as co-writing the film with novelists Aleksander Hemon and David Mitchell. “I’m very happy to have these characters back in my life,” Lana said at the time, “and grateful for another chance to work with my brilliant friends.”

Though there isn’t any news about the plot of the film as of yet, a release date of May 21, 2021 has been set, and actors Neil Patrick Harris, Jessica Henwick, and Yahya Abdul-Mateen will be joining Reeves and Moss in the cast.

2019 marked 20 years since the release of the original Matrix, which tells the story of a hacker, Neo (Reeves), who discovers that humans are trapped inside a simulated reality controlled by artificial beings. Last month, Brad Pitt revealed that he passed up the chance to play Neo. “I did pass on The Matrix,” he told journalists at the Santa Barbara International Film Festival. “I took the red pill. I wasn’t offered two or three, only the first one – just to clarify that. I come from a place, maybe it’s my upbringing, if I didn’t get it, then it wasn’t mine. I really believe (the role) was never mine.”
