Articles were annoying so here's the Wikipedia section.
Lord of the Rings (film series)
The Hunt for Gollum
Lord of the Rings: The Hunt for Gollum was announced to be in development on May 9, 2024 with a planned release in 2026. The script is being developed by Fran Walsh and Philippa Boyens and set to be directed by and star Andy Serkis.
I think the stipulation was no First Age, and anything new cannot impact the story of the Lord Of The Rings.
