When they're looking through some of Sadusky's locked up possessions, the book Riley Poole published in "National Treasure: Book of Secrets" is among the items, as is the Meerschaum pipe and Ben Franklin's "X-ray specs" from the original "National Treasure."
Three actors reprise their roles from the movies: Harvey Keitel as Sandusky, Armando Riesco as Hendricks and Justin Bartha as Riley Poole.
It was announced by Deadline on May 7, 2023 that the series had been cancelled after one season. Disney didn't give a reason for the cancellation.
