The Making of CLEOPATRA (1963) - This is the first part of the amazing story of the filming of the epic that changed Holllywood for ever.
This mesmerizing documentary appears in the 5 Stars Collection DVD of the restored movie. This is a fascinating account of a story as moving and tragic as the movie itself. One of the best "makings of" out there. It is mandatory viewing for any serious movie fan.
Unfortunately, Youtube blocked the second part of the video.
UPDATE: Here's the link to part 2, I uploaded it to Google Drive and now you can click on the link and download it; I don't know if you are able to watch it on the spot.
