Most expensive house (we could get into): Brentwood, Calif.

This hilltop megamansion is hidden away in the hills of Brentwood, California.

Listed at $18 million, this 13,000-square-foot home has seven bedrooms and 11 bathrooms, a guest house, and tons of custom features, including an app developed to control the home's lights, shades and more with the touch of a finger.

On the lower level, there is not one, but two movie theaters. The "summer" theater features a wall that can be lowered to an outdoor heated space.

And if you just happen to run out of vino while you're watching the latest movie, no need to press pause, the movie is already playing downstairs in your cigar room and wine cellar on a state-of-the-art projector screen.

Or step away from the movie and enjoy the home's oversized infinity pool, which has views of the Pacific Ocean.
