It’s been a big day for fans of The Matrix franchise. Neil Patrick Harris signed on to the upcoming fourth movie earlier today, and Deadline now reports that Jada Pinkett Smith may be joining the cast as well. Pinkett Smith played the role of Niobe in the second and third Matrix films, The Matrix Reloaded and Matrix Revolutions. In the films, Niobe is a rebel against the Matrix and the machines, as well as the captain of the Logos hovercraft. Not much has been revealed about the fourth Matrix movie, especially the plot, but here’s what we do know: Keanu Reeves, Carrie-Anne Moss, and Yahya Abdul-Mateen II are starring, and Lana Wachowski, of course, is directing and writing.
