I don't have much memories from this movie I saw on french TV a couple years ago.
The story is about a ship getting upside down, a group of people have to go to the bottom of the ship, which is now the closest part from the surface
They get maps from the ship that they have to read upside down in order to escape the drowning boat
At some point there is a man dying crashed by an elevator
I remember a big fancy room, with a lot of guests
It's in color
I swear this is not Titanic
