Similarities or coincidence?
I'd like to know if the director and writer, Måns Herngren, have possibly "lent" this theme from the japanese movie "Waterboys" by Shinobu Yaguchi?
(http://www.imdb.com/title/tt0299213/)
Judging from the trailer, it looks to be an "adult" version of the very same movie.
However, many of you reading this have probably never heard of "Waterboys", seeing as it is a Japanese movie and as far as I know has not travelled the borders all the way to Sweden. But I do recommend you to check it out if you ever get the chance.
Even if Måns Herngren or any other person involved in this movie hardly ever will acknowledge a possible connection between the movies, at least we can discuss the matter.
It would only be fair to credit the original author, one way or another. To most people, the theme of having male synchronized-swimmers will seem weird, but in a comical aspect, pure genius.
Not that I feel a need to diminish some of the "fame and glory" Måns Herngren probably will earn from this title, but I do feel a need to inform the public. They are then free to make their own assumptions.
"Lending" ideas has never been a new thing in movies. But lending a theme and overall plot development usually calls for some crediting to be done.
