"Charade" Blu-ray + DVD (Park Circus). Well, I've only compared the new DVD R2 by Park Circus and the the DVD R1 by Criterion, but, at least, they are a different transfer. The grain is less intrusive in the Park Circus, but apparently this is not due to DNR but to a different color coding and generally brighter image, which masks some of the grain. So, the Criterion DVD looks darker. Unfortunately, the Park Circus brightness also masks some of the detail in the faces: Audrey's pinkish glow, witch bothered some people in the resent "Breakfast at Tiffany's" Blu-ray, gets enchanced (the clothes, however, have fine detail). This is partly due to the source material and the original style of the period - "soft focus" was used to compliment the actors star quality.
In my opinion the Criterion DVD looks more natural than the Park Circus DVD, so perhaps Criterions Blu-ray (region A only) is just a little bit stronger, too? Notice also, that if you already own the Criterion standard definition DVD, the upgrade to high definition is not a great leap. However, if you have only seen "Charade" on tv or on one of those horrible public domain DVDs, you will be simply delighted with the Park Circus Blu-ray. So, nice work from the British company with good image presentation. Minus points for the lack of substancial extras or any subs. At least English subs would be welcomed in the European market, as many of us understand written English better than spoken English and are not used to following lenghty dialoque-scenes without some support from subtitles.
