I am commenting on the DVD version that I have now and I have not seen since 1963. There is a very big difference as in 1963 not only I was much younger but Cinema has changed. 55 Days was a Large Screen Movie compared with the Ten Commandments, Cleopatra of the same year 1963 and The Sound of Music and many others at that period. In those days of Cinema Hollywood convinced people to go to the Cinema with Movies that are not the same on Black and White TV on Small Screen. Watching it on DVD is not the same. Technirama an Advanced Technicolor, Dolby Stereo not as big as Cinerama. I specifically remember sitting in the cinema and the sound moved behind us. For example the Musical Bands in the opening scenes playing the anthems. About the History of China read the other comments. Still a very exciting Movie where a minority overcomes the Mass's winning at the end. David Niven does an interesting part that reminds me of the Guns of Navarone. Heston and most other actors do it very well too. Nine out of Ten in Sam's Scale.
