It’s exciting to see Shyamalan on such confident footing once more, all these years later.
"Last Action Hero" is about the same subject as almost every other feature film ever made: The possibility of blurring the line between the audience and the screen. We go to the movies so that we can vicariously live the lives of the characters who loom so glamorously above us, and the movies know that. Every moment of every shot exists with the full consciousness of the fourth invisible wall dividing the characters from their watchers in the dark.
Early in "Last Action Hero," a small boy is watching a movie when suddenly a bundle of dynamite comes bouncing out of the screen and lands near him in the theater. He runs for his life, but there is an explosion, and somehow he is catapulted through the membrane between the audience and the actors. He is in the movie. More exactly, he is in the back seat of a speeding car in a chase scene, and the driver is Jack Slater (Arnold Schwarzenegger), his hero.
The boy's name is Danny Madigan (Austin O'Brien), and he has seen all of the Jack Slater movies. He knows that Slater is always played by Schwarzenegger - which is more than Slater knows. One of the pleasures of this movie is the way Slater insists he lives in the real world, and how Danny tries to convince him otherwise by pointing out all the clues proving they're in a movie. All the telephone numbers start with the non-existent prefix "555," for example, and the good guys somehow never get killed, and all the women are dressed like models in a Guess ad. There is even a discussion of the Fallacy of the Talking Killer, often described in this space - that inevitable movie practice in which the bad guys need only pull the trigger, but make the mistake of talking too much, giving the good guys a chance to prevail.
Other movies have also played with the boundaries between reality and cinema. Woody Allen's "The Purple Rose of Cairo," for example, and Robert Zemeckis's "Who Framed Roger Rabbit." But they've used the gimmick primarily as a springboard for their stories for love and action. There is a lot of action in "Last Action Hero," but the underlying story never ever quite works. From beginning to end, the movie is about its gimmick, without ever transcending it.
