Ted Elliot has completed a first draft of the National Treasure 3 script, though it still needs rewrites. Elliot teases that, in addition to Ben, Riley, and Abigail, other familiar faces could return. The story of National Treasure 3 will feature an evolved relationship between Ben and Riley, and National Treasure: Edge of History is being treated as canon.

National Treasure 3 screenwriter Ted Elliot shares a progress update on the anticipated sequel, dropping some story and character teases. After the success of 2004's National Treasure, which introduces Nicolas Cage's treasure-hunter, Benjamin Gates, a sequel was released in 2007, reuniting the actor with costars Diane Kruger (Abigail Chase) and Justin Bartha (Riley Poole). National Treasure 3 has been in development for some time, but the project has struggled to get off the ground for years now, though numerous parties involved have expressed willingness to return, including director Jon Turteltaub.
