I won't regret anything, I have the Blu-ray preordered a long time ago. I'm specifically talking about when I want to watch and listen to the audio commentary. A normal viewing will be with the Blu-ray.
According to AFI, the movie was filmed in 1952 and RKO copyrighted it in December 1952. However, it didn't have its LA premiere or release date until February 1953.
I’m going to keep my DVD to watch the movie with Muller’s commentary because I think the video presentation of the DVD in 480p will be better than the 480i presentation on the Blu-ray.
