The trailer for this was just shown at Celebration 2023, but has not been officially released for everyone else to watch it.
Disney are doing its usual thing and taking down any videos online put up by fans on their phones at Celebration, but if you are quick you can still find some of them. It is almost as if Disney do not want any interested fans to watch the trailer for their own series.
'The show is set in the New Republic era, and will follow a group of kids lost in the galaxy trying to find their way home. It is described as a “Star Wars” version of some of Amblin’s coming-of-age films from the 1980s like “E.T.” and “The Goonies.”
Lucasfilm president Kathleen Kennedy said director Jon Watts “really got the tone,” which is in the vein of the Amblin movies Kennedy produced for Steven Spielberg.’
