Trivia / National Treasure: Edge of History

• The Cast Showoff: Jake Austin Walker (Liam) actually sings and plays the guitar. He did the Graceland scene without playback, tempo, or any assistance.
• Dyeing for Your Art: Catherine Zeta-Jones dyed her hair platinum blonde to play Billie Pierce.
• Role Reprise: Original National Treasure cast members Harvey Keitel, Armando Riesco, and Justin Bartha reprise their roles as Peter Sadusky, Agent Hendricks, and Riley Poole.
• Screwed by the Network: The show was cancelled after one season.
• Self-Referential Humor: In "Charlotte", Riley references being stuck on the same mystery for "three, four... fifteen years". This is a reference to the Development Hell the intended National Treasure 3 film, meant to pick up on the Sequel Hook from National Treasure: Book of Secrets, has gone through, as it has still not been made as of 2023.
