Largest projector in the world used to create 100-foot Dr. Manhattan

At 8:00 p.m. last night, Dr. Manhattan's 100-foot-tall ghostly visage hovered over the River Thames to herald the release of Watchmen.

The whole thing was pulled off thanks to an enormous water screen and the largest projector in the world. A shot of the Comedian's smiley badge was also projected onto the side of a building in London, as well as exclusive, specially-made footage to promote the movie.
