I fail to see where the previous reveiwer came to the conclusion of material available that could have been used in this DVDs release.
Being the UK's historian on "Raise The Titanic" of which I supplied (at the last minute) all that is seen in the 'special features' section, I can say that there is very little out there on this movie. There was no "official" making-of documentary made for this film, except for a promotional sales gimmick put together in 1980. Sadly this could not be used due to time contraints. No deleated scenes exsist anymore for this film, the original 12 minute sinking footage is currently in the hands of a private collector who will not release it and any "behind-the-scenes" footage (again) could not be used due to time constraints and copyright.
Before I became involved with the dvd, all that was going to be seen on the dvd was the film. And with the VERY little time I had to put together material from my private collection (including images not seen until now), the outcome for this release was far better than it was originally planned.
However, there is a possibility of a future release in a couple of years time of a "Special Edition" version of "Raise The Titanic", which will feature a lot more material from my private collection.
