I also recommend checking out other works by Takeshi Koike. Sadly, Redline was such a financial failure it almost bankrupted Madhouse and ruined Koike's reputation. Despite that he's a god damn master of animation and movement.

He did the opening to a little film called Party 7 which is a weird film about Yakuza and a peeping tom motel owner. But the amazing animation of the opening is well worth it. The film itself is...kind of off putting, but still moderately interesting.

Trava: Fist Planet this is pretty classic Koike. In fact the two main characters also appear in Redline.

World Record in the Animatrix. Stylish and a simple (by Matrix standards) story.

He's also done a lot of recent Lupin the Third films, which I haven't gotten around to watching yet. I've heard they're not well recieved, but I literally can't imagine they're bad, because he's made like 3 of them.
