Watch Billie Lourd Step In for Mother Carrie Fisher in 'Star Wars: The Rise of Skywalker'

Good Morning America has shared a short clip from Disney‘s upcoming behind-the-scenes documentary of Star Wars Episode IX: The Rise of Skywalker focusing on the late Carrie Fisher, with her daughter Billie Lourd speaking on stepping up to help with an important scene.

While J.J. Abrams and the crew were able to fulfill their promise of not digitally recreating the beloved actress, fans were surprised upon seeing a young Luke and Leia in the scene that depicted her Jedi training. The behind-the-scenes clip shows Lourd stepping into her mother’s shoes as the physical stand-in for the fight sequence, while CGI and editing techniques were utilized to put Fisher’s face from Return of the Jedi on to her body.

“It’s literally like a gift from her — or her forcing us to make her the star of the movie. Probably both,” Lourd said with a laugh. “Being back has been incredible, painful, surreal — all of the adjectives you could come up with, probably, I’ve felt.”

The clip also briefly touches on how the crew managed to fully include Fisher in the film despite filming after death. Daisy Ridley, whose character Rey shared a solo moment with Leia in the movie, can be seen tearing up as they prep to film the first scene with General Organa but without Fisher. “The reality of having to do a scene with someone who isn’t actually there was very difficult,” she explained. “I sort of had to walk off and have a moment.”

Watch the clip above. The documentary, entitled The Skywalker Legacy, will be included in the digital and Blu-ray release of The Rise of Skywalker on March 17 and March 30 respectively.
