Accordingly, the young actress was needed as a body double in the film. The shooting was said to have been a moving moment for everyone.
Even before Star Wars: The Rise of Skywalker started shooting, it was clear that all scenes with Leia Organa will come from unused material from Carrie Fisher that were already created in the surroundings of Episode 7 and Episode 8. Numerous elements of the last part of the saga also had to be rewritten after the actress's death. In an interview with Yahoo Entertainment Patrick Tubac (Industrial Light & Magic Visual Effects Supervisor) has now revealed that in a special scene from Episode 9, however, the makers needed a body double.
Spoiler Warning! Below are details on the story of Star Wars: Episode 9,
Billie Lourd was used as the body double of Leia Organa – Carrie Fisher's own daughter. In the course of the film there is a flashback in which we see Luke and Leia training together. Shortly before the end of the scene, the two take off their masks and we get a look at the young faces of the two characters. Mark Hamill played Luke and Billie Lourd stepped in as Leia. According to Patrick Tubac, this was a moving moment. Billie Lourd can also be seen as Lieutenant Kaydel Ko Connix in Episode 9.
