There were various HDTV broadcasts of “Titanic” prior to the 2012 re-release but sadly I haven’t managed to put my hands on an unedited version yet. I believe most of the TV broadcasts still airing today use the pre-2012 HD master (because they had to use an alternate take of the drawing scene to make it TV friendly). That may have changed though. It will be interesting to see after the recent re-release in theaters if we actually see a 4K Blu-Ray release anytime in the near future.
