Back in the 90's AMC theaters had a 70mm series where they showed West Side Story, 2001, Doctor Zhivago, and Ben Hur on their biggest screen. The chariot race is amazing on the big screen, the thing you don't pick up on the TV version is the shaking camera during the race. On the big screen...
As with the other big box releases, there have eventually been bare-bones releases...or retailer-exclusive bare-bones releases. Maybe Ben Hur will be the same.
I was fortunate to see a 70mm print of Ben Hur projected on a 40-50 foot screen, with good sound. The chariot race is something else on the big screen.
I ordered the disc-only blu-ray edition from Amazon.co.uk...I have too many big blu-ray boxes to fit on my bulging shelves.
