"National Treasure" (2004) and "National Treasure: Book of Secrets" (2007) centre on Cage's cryptologist character Benjamin Franklin Gates, who in the first movie finds a treasure map on the back of the Declaration of Independence.
According to Variety, Disney and producer Jerry Bruckheimer have tapped "Bad Boys for Life" writer Chris Bremner to work on the script for an upcoming third movie. Bremner previously worked on the first and second instalments, which were directed by Jon Turteltaub.
Disney chief Bob Iger addressed the potential for a third movie at the annual shareholders meeting last year (2019).
"I know that Jerry Bruckheimer who produced National Treasure 1 and 2 would like to make a third movie and I know that discussions about that film have gone on, probably since 2016, with our studio, but I know that they have not greenlit such a film," he said.
"They have talked about a number of different possibilities both on the creative side and from a timing perspective and I just don't have anything to announce, though I did speak with Mr. Bruckheimer not long ago about it and I know his passion for that franchise remains pretty strong. We love those first two films too, but we're not quite there yet."
