There’s always a hint of desperation about a project when there are sqauds of screenwriters attached. Here, Jim Kouf has a story and screenplay credit – and so do two teams of writers. But what might have hinted at a pig’s ear is actually a silk purse, and one that was made by Disney years before The Da Vinci Code was made. It’s the excellent adventure of Benjamin Franklin Gates, the supposedly delusional hunter who’s haunted by his family’s backstory from the Revolutionary War and in thrall to his grandfather’s stories of a treasure chest hidden by the Founding Fathers. It all hinges on clues on the back of the Declaration of Independence and is told with a sardonic tongue firmly in cheek yet ticking all the modern-day action-adventure boxes with brilliant use of city settings beautifully shot by Caleb Deschanel. With Nicolas Cage as Gates, Justin Bartha as the hapless Helper, Diane Kruger as the beyond-beautiful intellect and Sean Bean as the villain, this is great, smart entertainment.
