Hi I found this cool site called Al Pacino's loft.
GODFATHER DVD HIDDEN EXTRAS
(thanks romeox for this info)
There are some eastereggs on the Godfather DVD collection:
1. On the SET UP screen, arrow right from any option and a little Planet Earth will appear; press Enter and you'll be treated to a little 2-minute bit of Godfather clips in multiple languages.
2. Click on the FAMILY TREE, then go to "Santino (Sonny) 1916-1948", press Enter. On the next screen, again highlight the same choice ("Santino 1916-1948") and press Enter again - this brings up a screen on young and older Sonny. Arrow up and highlight the picture on the right (James Caan) and press Enter - this will bring you to an info screen on James Caan. Arrow left to highlight his picture and hit Enter to see a hilarious little clip of Caan doing a Marlon Brando impression as part of his screen test.
3. From the MAIN MENU go to GALLERIES and from that screen choose DVD CREDITS. There, hit NEXT four times and this will bring you to a scene from "The Sopranos" of the boys at the 'Bada Bing!' watching what they think is a bootleg DVD of The Godfather. A Great scene!
4. And there's another one, which can be found in the 'Filmmakers' section on the bonus disc. Go there and select '
Mario Puzo's' biography. Once you get there, press the 'Left' arrow key on your remote control twice and a large dollar sign will apear. It gives yo uaccess to a short clip, in Coppola asks the writer, why he actually wrote 'The Godfather.' Puzo's answer to it is quite revealing...
Quality is always the key, bro.!
