Evangelion creator Hideaki Anno has apolized for the delay of Rebuild finale Evangelion: 3.0+1.0. He's hinted that his attention has been elsewhere. He's said that he's been working on other projects. But, now, there is some indication that work is underway on the fourth part of the movie re-do of the seminal '90s anime.
Mechanical animator director and later chief animation director of the movies, Takeshi Honda, was at the recent MCM London Comic Con, where he spoke to UK Anime Network.
On the movies, he said:
There was a lot I wasn't able to do during the TV series, so I was actually willing to do the feature film version so I could do what I really wanted to do. Throughout all of the film series so far I feel that I've done that and I'm quite happy to do more. I still have loads more I want to do that I didn't do in the TV series, and the series is still continuing so there's more I want to do.
Having said that, I'm older now and I can't really do too much drawing with complicated lines as that's now physically very hard, so I'm just hoping for Evangelion to end properly before I retire!
And, he concluded by saying
We're actually working on the new Evangelion film right now. We're working hard and it'll come out eventually, so thanks for all of your patience - please continue to be patient, because it's going to be the last episode.
