There is a lot of special features on this DVD. You have the original theatrical trailer, A LOT of original pencil drawings and storyboarded sequences. There is also a lot of pictures where we can see the four Beatles. The interactive menu is also very cool ! Full of sounds and cool animations...even some hidden cool things!
We can see a couple of interviews with people who did the Beatles voices. They sounded funny, and a lot like the originals.
A thing I can say : If you want a good demonstration of what Dolby Digital is...you have to see this movie! The sound effects are really good, and it doesn't sounds like this movie was made in 1968 at all !! :)
