Adventure and exploration could be main themes. Diving into the unknown implies going to places not fully understood before, which is all about adventure.
I'm not sure which specific 'diving into the unknown true story' you are referring to. There could be many stories related to diving into the unknown. It could be about a deep - sea diving exploration where divers face uncharted territories, new species, and extreme conditions.
It depends. Sometimes works labeled as such might draw inspiration from real events but with fictional elements added. So, it could be a blend of truth and imagination.
Yes, it is. The movie 'Red Diving Resort' draws from a true story. This story involves certain events and actions that actually occurred in history, which the movie then portrays on the screen. It's an interesting way to bring real - world events to a wider audience through the medium of film.
