Steamboy (2004) IMDb
Ōtomo Katsuhiro (director).
Three generations from a family of inventors clash on the outskirts of a brief war between the British Empire and a US weapons manufacturer, in 1866. Meanwhile, Robert Stephenson tries to get his hands on a revolutionary new source of steam.
Steampunk action. A decent populist fruit of the subgenre, but shallow and suffering from a sagging half-hour finale.
