I’mSpencer, and I recently visitedWarner Bros. Studiosin England where they filmed theHarry Pottermovies.

1:24 scale model of the school, and they filmed it in front of a green screen.

The model is over 50 feet in diameter and took 40 different artists to build.

An additional 50 artists were then responsible for maintaining it throughout the production of the film.

Real gravel and plants and trees were also used to make the landscaping look as lifelike as possible.
