Bob Furmanek and Greg Kintz from the 3D Archive did the restoration on this title for Universal pictures. As far as I am concerned they should everyone's restorations from now on. For a titles over 60 years old you will never see deeper blacks rendered than in this blue ray. I have been burned before by sub par transfers like JAWS 3D & COMING AT YA. If you see 3D archive associated with a project you can buy with confidence.
