Nicolas Cage teaches us a little bit of history

Part Indiana Jones, part 24, and part junior high American history class (the one you probably slept through), Nicolas Cage’s adventure series has been a surprise hit among teens and adults. In this sequel, National Treasure 2: Book of Secrets, Cage’s investigator digs deep for the truth buried beneath the myth of Abraham Lincoln’s assassination. Things get personal when his great-grandfather is implicated in the plot, and he must go to great lengths to clear his family name. Diane Kruger and Harvey Keitel co-star. Rated PG-13. Out on DVD now.
