Smart, well-made thriller which appeals both to the Twilight/Harry Potter set and adult auds who enjoy intelligent action movies. BO should be sky high. For the unitiated, take the central premise of Battle Royale (1999 Japanese novel of teenagers fighting to the death for sport under a totalitarian regime), set it in near future America, then throw in elements from The Truman Show (1998 Peter Weir flick) and the overall story arc from Gladiator (2000 Ridley Scott film). Though it plays more like The Running Man (1982 Stephen King novel, 1987 Schwarzenegger vehicle) than Lord of the Flies (1954 William Golding novel). Jennifer Lawrence shows how Kristen Stewart how to act, though it’s clear the weak link is Josh Hutcherson (who plays Peeta Mellark), especialy if Peeta has a big role in the sequels.
