Collider recently caught up with How to Train Your Dragon 2 composure John Powell, who has been with the franchise since the very beginning. He reveals that DreamWorks Animation's executive producer Jeffrey Katzenberg is considering a fourth film, which will extend what was originally planned as a trilogy.

How to Train Your Dragon 2 is testing extremely well, and critics who have already screened it are raving that it's the movie of the summer. High praise indeed, but the team behind the movie feel it is going to be a big hit as well. In fact, director Dean DeBlois has already been confronted with the possibility of working on a fourth film.

This is what John Powell had to say about the prospect.

""I saw Dean in Cannes, we had a premiere of the film there, and he was very merry and a bit drunk and he sort of knew about [How to Train Your Dragon 3] and I think it was mentioned to him by Jeffrey that maybe they would do 4. And that was definitely, I think, a real kind of eye-opener for Dean and for me because it's like, 'Hey I thought this was a trilogy?' (laughs). So I don't know, and it might be good because he's got a lot of story left to tell, so maybe splitting it into two will work, but I just don't know about that yet. I'm supposing that at the moment, Dean has an idea for the third one and he isn't telling any of us yet."

Look for How to Train Your Dragon 2 to be a massive hit when it opens this summer.
