Luke Skywalker's Voice in THE BOOK OF BOBA FETT Was a Digital Replica of Mark Hamill's Younger Voice

The digital effects that were created to bring the younger version of Luke Skywalker to life in The Book of Boba Fett were pretty incredible! For the most part, fans were in awe as they watched Luke training Grogu in the last episode. It’s crazy to see how far technology has come and what it can do!

Well, it turns out that bringing Luke’s voice to life is all done digitally as well. Mark Hamill didn’t record any new dialogue for the character. Luke’s voice was created with the help of an A.I. program called Lola. Industrial Light & Magic Supervisor, Richard Bluff, recently spoke with Esquire and explained how Lola brought Luke to life. 

"They effectively reproduced a de-aged version of Mark for the shots by combining the texture from his face and also [the body double's] younger face. The biggest challenge for this sequence was that we weren't de-aging Mark in every single shot, and we had a variety of performances that Lola had to work on, too.”

Sound editor Matthew Wood went on to explain how they created the digital replica of Hamill's younger voice saying:

"It's a neural network you feed information into and it learns. So I had archival material from Mark in that era. We had clean recorded ADR from the original films, a book on tape he'd done from those eras, and then also Star Wars radio plays he had done back in that time. I was able to get clean recordings of that, feed it into the system, and they were able to slice it up and feed their neural network to learn this data.”

It seems like it would be so freakin’ cool to be a part of this, a part of bringing a younger version of Luke Skywalker to life that looks and sounds like a younger version of Mark Hamill! This must be super weird for Hamill!
