In the early 1950s, TV became a major threat to movie theaters. Hollywood fought back with Cinerama, an immersive, widescreen spectacle that viewers couldn't experience at home. Filmed in Venice, Madrid, Edinburgh Castle, Milan's La Scala opera house, from a rollercoaster and the nose of a B-25 bomber, hosted by Lowell Thomas, this splashy 1952 classic was seen by more than 20 million people in its original roadshow version. Restored with "Smilebox" curved-screen simulation and many extras. 2 hrs on 1 Blu-ray disc. Color and B&W.
