The Matrix 4 just scored another big star: Neil Patrick Harris has officially joined the cast.
Details about his role haven't been revealed yet, but it seems to be a supporting role.
We also don't know much about the movie's plot - but original writer/director Lana Wachowski will be returning to write and direct.
Original cast members Keanu Reeves and Carrie-Anne Moss are also on board, as well as newcomer Yahya Abdul-Mateen II (Aquaman, Black Mirror) in a leading role.
Production will begin early next year.
