Tuesday's death of actress Carrie Fisher, who played Princess Leia in "Star Wars," set off waves of remembrance among fans — but also speculation over her character's return in yet-to-be-filmed episodes.

Filmmakers are tapping advances in digital technology to resurrect characters after a performer dies, most notably in "Rogue One: A Star Wars Story." The film, in theaters now, features the return of Grand Moff Tarkin, originally played by a long-dead actor.

The trend has sent Hollywood actors in the here-and-now scrambling to exert control over how their characters and images are portrayed in the hereafter.
