I don't quite remember how I happened across the work of Leo Kim.
Leo took that series beloved of every young boy, and came up with his own episode titled 'Thomas Tank Mad Bomber'.
Leo must have known he was on to a big hit: boys (big and little) love trains. And explosions.
Personally, I think the Thomas series was always begging for a good explosion. You only ever had to watch an episode or two of the original to recognise that here was one seriously vindictive shedful of steam engines. A sudden malicious flame-burst was only ever a toot-toot away.
While the episode itself is worth the watch (gotta love the droll humour that follows after 1:30), even more fascinating are all the 'making of' videos that Leo has done to showcase the challenges of film-making with model trains on a shoestring.
It's clever stuff. Even if Leo is Victorian.
