I wouldn’t mind a Leia film or show. Its hard to replace Carrie though its quite impossible. I feel bad for what ever actress has to step into this role and will never be able to exist in the same space in people’s minds as Leia did in Star Wars 77. On the other hand i would prefer a new actor/actress instead of cgi.
A new young Leia has already been cast, the little girl from the bird box movie with Sandra Bullock. She will show up in the Obi-wan Kenobi series, as well as a young Luke Skywalker.
She could return later for her own series, if they decide to go down that road, or she could show up somewhere else in another Star Wars series set 8 years BBY. Maybe even in Andor, filmed around the same time as Kenobi.
