Interesting thing... I asked Sagardoa month ago about underwater scene (I had some very vague intel/rumour ),
and he replied that there is no such scene. His reply was definitive, he was quite sure about that...
And then again, do you guys remember the photo of underwater weed some crew member posted a while ago on Instagram? Some details about all those claims of people who watched the movie on screenings are so confusing and not completely coherent...!
