The Matrix Resurrections has a totally different visual style than the original trilogy, but there’s a reason the fourth Matrix movie has its own aesthetic. 18 years after the release of The Matrix Revolutions, Lana Wachowski finally returned to the franchise for a fourth film. Warner Bros. had been clamoring for another Matrix movie for years and, as Wachowski pointed out in The Matrix Resurrections itself, the studio essentially threatened to make a Matrix movie with or without her. Wachowski co-wrote the script for the fourth Matrix film with Cloud Atlas’ David Mitchell and The Lazarus Project’s Aleksandar Hemon.
