The film "The Lord of the Rings: Gollum's Hunt" will feature digital de-aging of characters. Director Andy Serkis confirmed that machine learning will be part of the process. However, the film will still utilize traditional filming techniques and is not created solely with AI.
Serkis did not specify which actors will be de-aged. Since the filming of "The Fellowship of the Ring," over 25 years have passed for some returning actors, including Elijah Wood and Ian McKellen.
