Both editions are pretty similar in the image category. If you look at the bit-rates I would guess they were from the same print and not a lot done to them in conversion to digital. A bit of contrast boosting, but that is about all. In some captures the UK edition looks better (sharper) and in others the Anchor Bay looks superior. Overall I like the contrast levels in many scenes of the Anchor Bay... pitch black at times. Someone has the ratio slightly off in one of these DVDs as the faces are fatter in the Prism PAL edition and thinner in the Anchor Bay. My eye says the Anchor Bay is closer to reality, where yours may say the opposite. The Extras are totally in the Prism favor making them much like a Criterion, except lacking the inclusion of a commentary. Interesting that like one of the Criterion Hitch's (Rebecca), Prism has shown the titles as picture-boxed. This film is not really considered a Hitch classic, so I would imagine very few who own the Anchor Bay will buy the Prism just for the extras... but they do have that option.
