The LD of the Complete Showboat Collection had an almost complete version of the 1929 version. The prologues that are on the Criterion blu-ray were not complete on the LD. I still have that LD, so most of the movie still exists.Ava Gardner's voice is just fine. I'm not sure why they dubbed it. What is left of the 1929 version has been cobbled together on the Criterion 1936 version. It's interesting. Looking forward to seeing and hearing this one.
