A great interview with and concept art from the creators of the opening title sequence for HBO's Game of Thrones, including some cool anecdotes for makers and pitchers of things:
Early on, we did a test render of the Red Keep, which is the main structure at King's Landing. We placed the fully rendered model on a CG board skinned with a sample of beautifully damaged plywood, and showed it to the executives. Somebody said, "We didn't know that you guys had a workshop." And at that point we knew we were on to something... that the artists working on the sequence had really started making something extraordinary.
