Did you know that in Titanic 1997, take out all the modern day stuff with old Rose telling the story, and all the 1912 stuff is the real life 2 hrs 40 mins sinking timeline? Director James Cameron must have worked that out on purpose. ;) The Lemon Tea scene with Captain Smith represents visibility. The Lemon in the Tea cup under the Tea is like the iceberg under the Ocean. Every scene James Cameron made has a purpose.
