Fridge Horror: The O'Hara Foundation's Steam Troopers. Men in metal suits were probably getting severe burns with those steam engines on their backs, given the overall quality of the Foundation's inventions.
Inferred Holocaust: London is saved when the steam castle explodes in the Thames but then you realize that a good chunk of London was frozen, blown up, and smashed during the latter half of the movie. Not to mention the flooding when the frozen clouds of steam melted. Regardless of how many weapons the foundations manages to sell, the British government will, at the very least, sue the living pants off the foundation for damages inured to their capital.
Magnificent Bastard: Edward "Eddie" Steam was injured in a steam accident. Rebuilding himself into a metal Cyborg, Eddie decides to build steampunk weapons of war, with his Magnum Opus being a giant floating castle, which he proceeds to pilot over London. When his son Ray and father Lloyd try to destroy it, Eddie proclaims that it will still inspire people, given that it has been revealed to the world. Later he ends up helping Lloyd and Ray destroy it over the Thames. While Lloyd tries to cut off his escape, Eddie manages to evade him, and it is shown that his prediction was true, given that the world goes through a steampunk revolution.
Superlative Dubbing: Christ yes. The dub got the British Accents spot on, either from actual British actors or American actors doing extremely accurate impressions of them. Patrick Stewart and Alfred Molina steal the spotlight every time they're on-screen, hamming it up in the best way possible.
Tear Jerker: Quite a few scenes involving Scarlett, as she struggles between the ideals set forth by her parents with the O'Hara Foundation and the ideals set forth by the Steam family.
The climactic battle sequence is filled with War Is Hell moments, particularly during Scarlett's walk on the battlefield, in which the pavilion's shattering glass replays her and Ray's excursion there the previous night, and realizing that the Steam Troopers are actually people, rather than automatons.
, and they date all the way back to the first century, though they were nowhere near as powerful as the one shown in the movie.
