Ray is a young wunderkind inventor living in Victorian England. His life is turned upside down when he receives a special package hailing from the United States, sent by his grandfather, Lloyd Steam. The package contains a device called a Steam Ball, a device so powerful that it can drive any machine that requires steam with a nearly limitless amount of energy.

Ray is instructed to not let the Steam Ball fall into the wrong hands, which include the mighty O'Hara Foundation, who desperately want to bring the Steam Ball back into their control so they can achieve their less than noble goals.

He will need to use every bit of his brilliance in order to dodge the countless goons that are sent to snatch the device from him. It will be a battle between good and evil, a battle for redemption, a battle for the future!


Steamboy won the 2004 Best Animated Feature Film at the Catalonian International Film Festival.

The premise of this movie is that steam is a ridiculously powerful source of energy (which it kind of is when you think about it) and that in Manchester, England a boy named James Ray Steam ends up receiving a metal ball filled with powerfully concentrated steam from his grandfather, Lloyd Steam. He can’t let it fall into the wrong hands or its immense power could be used to take over the world (or something of that sort). This movie features top-notch animation, great voice-acting (especially in the English version, surprisingly with the likes of Patrick Stewart), and a story that is easily comprehended by ...

Mixed Feelings
The good first. The cgi and animation hold up almost 20 years later. It really is a beautifully shot and designed movie. The compositing basically seamless and the effects animation is gorgeous and had me gasping as you can feel the weight of giant machines fly and fall apart. This all pains me to rate this movie so low given the technical prowess.

The Bad. Everything else. The story, the plot is mid, the pacing is slow. There are no redeeming characters, they are all frustratingly incompetent and either terrible humans or too stupid to still be alive. There are several scenes where our hero is ...

Story: The retelling of history has been done many times in various series, it can be fun a lot of times, but Steamboy really dropped the ball this time. Many times actually, Ray just couldn't keep a hold of it. [oh snap, a pun] *ahem* I'm still not really sure what they were trying to do with the story. Apparently the kid's father had some skewed view on science and decided to start a war with Britain. There wasn't much of a lead up to this, it just kind of happened at some point. There are far too many obstacles for Ray. Each time he ...
