The Rundown, in which Johnson plays a mercenary named Beck doing dirty deeds for hard cash, is no more than a passable diversion, a live-action cartoon in which things go boom and nobody bleeds even when rendered Swiss cheese by a machine gun or pummeled by the flying fists of a dozen natives swinging from ropes. (The movie's about as sensitive to its indigenous people as a Tarzan film.) It's a summer movie released in early fall, sent into theaters after the explosions of July and August have simmered down. Expect nothing, and you will be rewarded kindly, especially by Christopher Walken as a tyrant who apparently has an entire South American country digging for gold in the computer-generated canyon behind his hut. Walken hasn't acted in decades, choosing instead to offer up the best Christopher Walken impression on the planet; he elicits titters before even opening his mouth.
What's most revelatory about the movie, which finds Beck dispatched to the Amazon to return a conniving fortune-seeker named Travis (Seann William Scott) to Los Angeles, is Johnson's performance -- as in, he actually gives one. In his first role, in The Mummy Returns, Johnson didn't even speak (English, anyway) and was seen for a few taunting seconds; in his second, as the title character of last year's The Scorpion King, he said next to nothing and wore even less (though not as little as his female co-star, who looked one stiff breeze away from rendering the film a Vivid Video production). The Rundown was being developed for him even before he'd finished filming The Scorpion King, and it's his first real attempt at holding a movie, which he does -- in a choke hold. You can smell what The Rock is cooking: a career in the movies, and it is well done.
The film, directed by once-and-future actor Peter Berg of Chicago Hope, aspires to be nothing more than an Indiana Jones knockoff, replete with villains wielding bullwhips and gold statues obscured by deadly puzzles; it travels a familiar dirt road that looks more like a rut and feels just like a ditch. But Johnson, who was computer-generated in Mummy and only looked it in Scorpion King, keeps it engaging, displaying a comedic knack first revealed during his Saturday Night Live appearance in 2000. He has the timing of a Rolex, even when playing straight man to American Pie's Stifler, who now sports a beard to suggest his own ascension into adult roles and has grown no less exasperating with a change of scenery. For her part, Dawson speaks in an accent that suggests she's the only Jamaican in South America; little wonder she acts like a woman who lost her compass.
So it's left to Johnson to keep the movie from flying into the breeze like refuse, and he does only because he's genuinely witty and not afraid to try anything once, even if it means letting a monkey hump his leg (an homage, perhaps, to Chris Kattan's Mr. Peepers). In one scene he devours a hallucinogenic fruit that renders him paralyzed; he's unable to speak and can only mumble, which, for a man who's made a fortune delivering smackdown soliloquies to arenas, is awfully funny.
Early in the film, Beck strolls into a nightclub to shake down a college football star who's late on paying a gambling debt. The techno music booms, the neon lights blind, and what happens next is fleeting and bewildering but unmistakable: As Beck walks in, he bumps into Arnold Schwarzenegger, who turns to Beck, grins and says, "Have fun." Beck responds only with a puzzled look, a delighted what-the-fuh? -- maybe Beck didn't understand what he said (we barely do), or perhaps he thought Arnie was on the campaign trail trolling for the disco vote. But what's perfectly clear is that the passing in the hallway is a passing of the torch; The Rundown, which aims to beat a laugh out of you, is the kind of film Arnold would have made early in his career, maybe after Raw Deal, which The Rundown isn't.
