Please stop the confusion. There won't be a 'wide-screen' version of the movie. Not here, not in Germany or France, not in the U.S, where the film will be released on March 17th.
Quo Vadis was made prior to the advent of widescreen projection and stereophonic sound. It is presented, as in its original theatrical release, with a 1.37:1 aspect ratio and monophonic soundtrack. Because of its extreme length and detailed photography, WHV has spread the film over two discs in order to maximize bit-rate and insure the highest quality picture presentation.
This is the best version you can get for a long time, so sit back and enjoy,
