I had never heard of an official work print being in existence for Thunderball or any of the Pre-70's Bond's.
I do bet that The Ian Fleming Foundation sure world like to get their hands on a Thunderball work print if it truly exists, and would compensate the barer handsomely!!!
The IFF states on the Inside Thunderball segment of the SE DVD that there was a major deleted scene where Bond has a tour of the Disco Volante, but no footage of that segment is still in existance. Only a few productions stills remain.
The "Things I Do For England" Deleted Segment that I will have on my DVD was created by me using the Pan & Scan
Laserdisc and the Television Trailer that contains the rare out-take footage. The video has been color corrected as best we can
for optimal visual presentation for a composit. The entire segment is about 60 seconds, and 100% Fanfiltration made.
As for any other extras, this project is busting it's seams as it is. But exception will allways be made for any truly valuable Bond rarities that may drift into the Fanfiltration studios.
More to come...
