How to Train Your Dragon 3 is currently slated for release on March 1, 2019.
It may also indicate that How to Train Your Dragon 3 is still intended to close out that narrative arc, as was suggested a few years ago before the film was pushed back to 2019.
This is what I’ll say, and for whatever it’s worth I do swear that this is not just promo nonsense.
It’s the movie that the series requires and deserves and it’s the rightful third chapter or third act, I should say.
