In fulfillment of the prophecy that Disney will eventually remake every single one of its live-action movies, here is Race to Witch Mountain. It bears a passing resemblance to 1975's Escape to Witch Mountain, but it's more reminiscent of a tiresome carnival ride whose operator abandoned it and left it to run for 90 minutes. Whatever fun there is in it quickly gives way to tedium.
Appropriately, it's set in loud, gaudy Las Vegas, where Jack Bruno (Dwayne Johnson) works as a cab driver. In the past he has freelanced his services for one Mr. Wolf, a shady underworld figure whose goons regularly visit Jack trying to re-enlist him. Maybe I shouldn't bother mentioning that, though, because it ultimately has nothing to do with the story. For that reason, I'm also not going to mention Jack's lifelong desire to own a particular Ford Mustang, since that detail was clearly added only after someone read a screenwriting book and paused at the chapter that talked about giving your characters hopes and dreams. It's extraneous.
But back to the actual story. Jack encounters two strange preteens, a brother and sister named Seth (Alexander Ludwig) and Sara (AnnaSophia Robb). They are extraterrestrials whose spaceship crashed in the desert when they came to Earth in search of a MacGuffin, and now they must get the item and return to the ship -- which is problematic, because the U.S. government, led by heartless Henry Burke (Ciarán Hinds), has recovered the craft and hidden it away somewhere. There's also an alien assassin pursuing the kids, though that's another thing that's ultimately not particularly relevant.
