I was getting ready to buy the Blu ray of Event Horizon and did a quick check and found this image (just as a comparison, as the entire movie would be this way):
From Blu-ray.com
Compare this to the original DVD release (which should be the same as the LD):
So if you didn't notice the difference by now in the top pic, in the forum for this title at blu-ray.com it's been discovered that the image has been stretched for this release (and someone also suggested the 2 disc DVD release as well). Also note, the contrast has been upped a few levels and has changed some of the gray tones and shadows to white (notice some of the blue is now totally white in this scene)--which I could live with as it does up the detail significantly, but I'm just not sure I can live with coneheads playing these parts!
They're reporting the Blu ray release as 2.35:1 which the framing does look correct at least from this image, so I'm not sure exactly how they've botched this one up. There appears to be more image to the left of the frame and possibly to the right. I tried to time the DVD capture to match the exact timing of this shot from blu-ray.com. Did they take a 1.85 cut from the master and stretch it to 2.35? Maybe they didn't use the original print? Also, there's been a re release this year, unfortunately, I think it's the same cut as the first Blu ray with this error. Don't get rid of your LD or original DVD copies just yet.
