Din Djarin's latest arc wrapped up its third season in the spring, and rumors about what's next for him and his young apprentice are ramping up. While promoting the latest season, showrunner Jon Favreau revealed he's already finished writing the fourth season. The Mandalorian typically starts filming seasons in the fall, but due to the WGA and SAG strikes, it's unclear if that will be the case this time. According to Making Star Wars, Lucasfilm is exploring the possibility of turning The Mandalorian Season 4 into a film. Series executive producer Dave Filoni might also direct The Mandalorian movie along with his New Republic feature if the studio proceeds.
