Sopranos, Fun Clips, Audition Tape:
On the bonus material disc there's a hidden scene from an episode of "The Sopranos" when they are trying to watch The Godfather movie on DVD. All you have to do to access this feature is to choose "Galleries", from where you choose DVD credits. Keep pushing the next button through all information until the scene starts.

On the bonus material disc select Set Up. Once in that menu click to the right and a globe will appear. Click enter for a humorous clip compiled from various scenes.

Also on the bonus material disc, there is a little humorous clip hidden in the Mario Puzo biography section. It's a big dollar mark that becomes visible if you look around a little.

Again, on the bonus material disc, In the family-tree section, click first on Sonny, then on the picture on James Caan, and then on the second picture of Caan, and you'll find a little audition clip with Caan.
