It was originally reported that Lucasfilm was planned an animated sequel series to Star Wars Rebels, finally revealing what happened to Ezra Bridger and Grand Admiral Thrawn. The Mandalorian's second season set the stage for that story to play out, but the overwhelmingly positive reaction to Ahsoka Tano's live-action debut seemingly changed plans (and Ahsoka will now serve as that sequel).
This means Lucasfilm will need to find actors to play both Ezra and Thrawn, and we may finally know who the studio wants for the former.
According to the reliable folks over Kessel Run Transmissions, Aladdin star Mena Massoud is the current frontrunner to play Ezra in the Disney+ series, which would be stellar casting decision on Lucasfilm's part. We've been waiting to see what would come next for the actor after his star-making turn in Guy Ritchie's live-action Disney movie, and playing this Jedi could put him on the map in a big way.
It's no secret that Lucasfilm has been on the hunt for a diverse actor to play Ezra, and with Dave Filoni in charge of Ahsoka, he clearly sees something special in Massoud to zero in on him for the role.
Nothing is official yet, of course, but we'll hopefully have much more to share with you soon.
