One thing is clear though – everyone involved in the new production is under a lot of pressure right now. “Frozen” was a massive hit when it came out, and people are still talking about the film from time to time, so it was obvious that a sequel would immediately receive a lot of attention.
So the people behind “Frozen 2” now have to meet some very high expectations with their work, and this can easily take its toll on a person. Hopefully everyone will be able to handle their duties accordingly, however.
The film is expected to be ready for a 2018 release, but this hasn’t been officially confirmed so far. Given the long period of time until then, it’s entirely possible that the release schedule plans might change, but we’ll find out about that as time goes by and 2018 approaches. In any case, we don’t expect to hear much about the production until at least 2016-2017.
