yes there's going to be an offical h2O just add water movie to take place either after season 3 または after season 4 if there is another season. The movie is all new h2o and they haven't filmed it yet.
yes and no there are two 映画 but they are only mash ups of episodes (one movie per season) so yes there are 映画 but no they are not new stories just kind of a recap of the season
