^I've seen that. I'm hard-pressed to name any longer anime. I think the problem is that anime is almost always serialized, but then frequently later collected. So for example, I have a "movie" of the classic anime OVA Casshan which is 1h53m long.... only not really, because that's actually a compilation film of the 4 episodes that were released separately. Most gaijin writing about Eastern animation don't know the release history of these, so it's hard to sort out what should actually be considered the film release or what's an original, etc. Hence, you see the qualifier "Western" but you don't see anyone saying that this or that "Eastern" film is actually the longest ever. I don't think anyone knows.
