After traveling to the far reaches of East Los Angeles and Burbank, Calif., Disney offered journalists one more set visit for "Race to Witch Mountain." This time, I witnessed a massive set constructed in a warehouse north of Los Angeles in suburban Santa Clarita, Calif.

This most impressive of the three "Witch Mountain" visits was to a set that looks like a modern government base (could it be Area 51?) where the film's two teenage alien heroes, Tia (AnnaSophia Robb) and Tony (Alexander Ludwig), have been captured. First up is a scary examining room where government scientists are ready to pick and probe the good-natured young aliens. However, attracting the most attention is a life-size replica of the youngsters' ship (old-school flying saucer design à la "Indiana Jones and the Kingdom of the Crystal Skull"), which is central to today's scene.

Warning: Spoilers ahead!

Joined by their cab-driving protector (Dwayne Johnson), and a sympathetic scientist (Carla Gugino), the teens walk up a ramp into the ship with the intent of flying out of the complex. As they're almost inside, they turn to find Ciaran Hinds, who plays an evil government agent intent on dissecting the kids, and his squadron of soldiers ready to fire. Hinds tells them to surrender, but Johnson's character refuses. The guns go off (loud!), but the teens' powers allow the bullets to pass through everyones' bodies without harm. Before Hinds and his cronies can react, a huge explosion goes off behind the ship (louder!), and the soldiers race to discover what it could be (how about an alien-hunting killer?). In the confusion, the four heroes enter the ship and director Andy Fickman yells "Cut!" Fun stuff, for sure.

During previous visits, Fickman and producer Andrew Gunn talked about this new version of "Witch Mountain" being more in the vein of a nonstop action flick such as "The Bourne Supremacy." Today's scene is the first time I see that vision and, for leading man Dwayne Johnson that direction was key to his involvement.

"I said for a long time that I didn't want to go back into the action genre unless it was intense action that really played well, like what [Paul] Greengrass did with the 'Bourne' films and what [Martin] Campbell did with the latest Bond movie," Johnson says.

Johnson, 36, has worked with both Disney and Fickman before on the family comedy "The Game Plan." Although the duo wants "Witch Mountain" to be much more male-friendly than "The Game Plan," they know any leeway they have is because Disney has allowed them to "really push the envelope."

Johnson remarks, "A lot of my movies in the past have really been intense, and Disney, to their credit, [are] really not afraid to take those elements and combine them and merge them with all the elements that make Disney great -- you know, family and heart and humor, touch of fantasy."

The original 1975 "Escape to Witch Mountain" has something of a cult following, so Johnson and Fickman should get a good idea of how well their new "vision" will be received after they preview some scenes at this week's Comic-Con International in San Diego.
