This is an atrocious quality print - like it's just been transferred from an ancient video copy. It's been chopped into 4:3. It's also dubbed into English. Avoid and wait for the Criterion edition to come out.
I too was disappointed to find it in English. There should be some notification if the copy is dubbed. I didn't know what to make of the picture quality - whether it only existed as poor quality. The historic footage at the start is often impossibly dark. It's a very interesting film with a great performance by Sophia Loren but the copy is of substandard quality.
All the other reviews in this website dis the movie due to the DVD's quality. The Bluray version is now available at cinema paradiso, and it's widescreen (no pan-n-scan), the bw intro is clear, the sound is the original italian, but you can chose to have the dubbed american version is you wish. There's also two 1.5hr documentaries.
