This seems to be different from Filoni's Mandoverse movie. This one is to be directed by Jon Favreau and produced by Favreau, Kathleen Kennedy, and Dave Filoni.
The Mandalorian & Grogu will go into production in 2024.
Nice! Hopefully, this production has better luck than the last few planned movies. Considering this is directed Favreau, features Mando and Grogo, & production is starting this year, signs are looking good.
Hopefully, it ends up being better than S3 of Mando, too. As of now, I'm cautiously optimistic and excited. It'll be fun to hear more about this. It's been a long drought for SW in theaters, and longer still since a good SW movie was in theaters.
