"Young Frankenstein" on BLU RAY - Compatibility Issues On The 'US' Disc...,
This review is from: Young Frankenstein [Blu-ray]  [US Import](region A) (Blu-ray)
I saw this at the cinema (back in the day) and was amazed. In fact anything Mel Brooks and Woody Allen put out at the time seemed to be dripping in anarchic magic.
But if you're buying on BLU RAY - stick to the UK issue – this may sound obvious but Region Coding rears its ugly head. The American version on 20th Century Fox is REGION A LOCKED – so it won't play on our machines unless they're chipped to be 'all regions' (which few are).
The UK variant is cheap too and has a very good print. Stay with that…
