The teaser trailer for producer Jerry Bruckheimer and director Jon Turteltaub’s National Treasure follow-up, Book of Secrets, is online and in theaters, and though extremely short on action, it does a decent enough job dizzying up a plot of conspiracy centering around Abraham Lincoln assassin John Wilkes Booth, and 18 missing pages from his diary — pages which doubtlessly do not include a simple list of family muffin recipes.

Starring Nicolas Cage, the original National Treasure, from 2004, was a throwback treat — one of those rare PG-rated adventure flicks that still legitimately work for audiences above 14 years of age. It was also something of a surprise smash hit, nearly perfectly halving its $347 million box office haul between domestic and international receipts, despite the fact that its plot centered around desperately American items and contrivances, like stealing the Declaration of Independence. Future trailers will no doubt pump up the adventure in leaping fashion; full of shots of Cage pulling open shelves and peeking around, this one was for the parents. To that end, the cast, too (Harvey Keitel, Ed Harris and Oscar winner Helen Mirren, plus a returning Jon Voight), gives this project a sheen of respectability that helps mark it as terra firma for adult audiences.

Pushed back a month from the Thanksgiving perch of the original, Buena Vista will release Book of Secrets on December 21, and hope that the aftertaste of The Blair Witch Project follow-up Book of Shadows has abated. Again, to access the film’s teaser trailer, click here.
