Titanic *spoiler*
I saw this movie the other day and nearly fell off my chair. I am not accusing James Cameron of plagiarism, but that shot below decks with the white woodwork and wood doorways, water pouring down stairs, and the floating tables and dishes...or about to float anyway...it was so similar. It makes sense in any event. You can only shoot a hallway from so many angles, water always pours through a ship, and ships of that era had that beautiful white and wood look to them.
So I believe instead that both artists were inspired by the Titanic, and that there is a shared unconsciousness in this life. It is possible that earlier Titanic or ocean disaster films also had these aspects to them.
It just amazed me (NOT MALICIOUSLY) how often people have the same vision as well as their own. I suppose this is how we all communicate and are fortunate to create memorable works. We "see" with some same inner eye. I think it's great.
