You may recall a Japanese animated movie titled Steamboy back in 2004. I just saw it a second time on cable this week and realized how useful to the Victorian sci-fi wargamer. Now the movie was a 10 year effort of Otomo the creator of Akira. As a movie it was a flop. The story line is rather simplistic, but the real letdown IMO was the 2d dimensional characters. The London landscapes and steampunk vehicles are superb.
The British tanks are my favorite design of this film.
