Hi,
That info is quite out of date. Pretty much any new release is made from a much higher quality process. That T2 version was digitized at 1080p anamorphic, now they do 4k scans.
The "How I Learned to Stop Worrying and Love the Bomb" remaster in 4k:

There are even movies done at 8k scans from 65mm film, like Baraka.

in 2007 the original 65 mm negative was re-scanned at 8K (a horizontal resolution of 8192 pixels) with equipment designed specifically for Baraka at FotoKem Laboratories. The automated 8K film scanner, operating continuously, took more than three weeks to finish scanning more than 150,000 frames (taking approximately 12–13 seconds to scan each frame), producing over 30 terabytes of image data in total. After a 16-month digital intermediate process, including a 96 kHz/24 bit audio remaster by Stearns for the DTS-HD Master Audio soundtrack of the film, the result was re-released on DVD and Blu-ray Disc in October, 2008. Project supervisor Andrew Oran says this remastered Baraka is "arguably the highest quality DVD that's ever been made".[1] Chicago Sun-Times critic Roger Ebert describes the Blu-ray release as "the finest video disc I have ever viewed or ever imagined."[2]

Newer movies are using all digital filming in 5k. They are so clean looking that often, artificial noise is added to them. This was done in Knowing, and also in some animations.

The film will also be the first Hollywood production to be filmed with the RED Epic camera, and is being shot in 3-D at 5K resolution.[69] Cinematographer, John Schwartzman had this to say about the camera:

"Today was Epic, Monday December 6 marks the first day the Red Epic camera was used to shoot a major studio motion picture. I can say for certainty the camera does exist and boy is it ready for primetime, as a matter of fact it's a true game changer."

Even these will be out of date soon, TV at UltraHD resolution are now available, they are 4320p (8k). I'm sure production will move to 16k to make a good down-sized image for it. We will see yet another round of remastering. At 33megapixels, UltraHD is pretty serious resolution, even for professional cameras. It's similar to IMAX.

Parts of Dark Knight were done in IMAX. See if you can notice - I noticed it right away without even knowing the details (near the beginning.. the rocks on the roof of the building.. that part looks different somehow).

Thank you very much for your input - especially for the Wikipedia links, which I found very helpful! :)

You're welcome guys. I've spent some time reading about this stuff, is there anything else you are interested in? It's pretty easy for me to whip off links because I know where to find stuff. I had the impression the OP was on a quest for quality. I also find the description of the efforts they go through for film restoration interesting. Read about the restoration of Metropolis (1927), it's a great story.

I could also mention that the Red Epic, used for filming The Amazing Spiderman (2012), is a bayer pattern camera, meaning that half the resolution is in the green and the rest in the red and blue colors. That means there can still be visible improvement by going double the resolution and downscaling to the output format, so 5k isn't really enough for 4k cinema projection.

What is the 5k? Never heard of ..

5k is referring to 5000 or so horizontal pixels. They use a different convention for referring to resolution than we do in other fields; in cameras it's megapixels, in video it's vertical resolution.
The Red Epic has up to 14megapixels, or 2700p, or 5120 horizontal resolution, though you wouldn't make a film with the full resolution unless you had an anamorphic lens.
The 4k cinema projection standard is 4096×2160 or 9 megapixels, or 2160p.
The resolution of 35mm film is claimed to be approximately 4k.

Bad writing, my fault.

I know what 2k and 4k (actually there are several 2k and 4k standards) mean :) but I never heard of a 5k resolution in this field.

PS: The maximal resolution of 35mm 4perf in ideal conditions is close to 24Mpixels (sort of 8k).

This common technique- nothing special. It's also an old article.

@jmac698. Nice info buddy. Very helpful. Hey can you know when the blu-ray of meckena's gold and Lawrence of arebia become available any info regarding them. Also why we require red green blue colour, film can capture any colour as it is! or that red camera has digital sensor .

@kolac. Ya it is common technique ,but i liked the effort taken by THX. Also i have seen many badly remastered Dvd even with finger prints. And continuous scratch on film running all over the film.

@vrpat
Our eyes naturally see color by the combination of 3 colors.
http://en.wikipedia.org/wiki/Color_vision#Wavelength_and_hue_detection (a bit technical, just remember cones see 3 colors)

Color film tries to match this by various ways; early color film used just two colors. To view this effect at home, just unplug the blue cable of your component video connection; you can hardly see the difference.
http://en.wikipedia.org/wiki/Technicolor#Two-color_Technicolor

Modern color film uses 3 colors,
http://en.wikipedia.org/wiki/Color_motion_picture_film#How_modern_color_film_works

so do cameras.

thanx @jmac698
what is production cost of creating blu-ray the THX way (just asking)

4k scanning of a feature length film is 2250 euro, from one quote
http://www.charbon-studio.be/pricing#Digital-Intermediate_Charbon%27s+Services

Specs of a 4k film scanner
http://www.lasergraphics.com/us/pages/directorfeatures.htm

As you can see with the new scanning technology, there's no video camera so the concept of an anamorphic lens makes no sense anymore.
I didn't check exactly how they work, but my guess is that they shine a small dot across the film and a light sensor reads the brightness at that spot.

6k film scanner
http://www.arri.com/digital_intermediate_systems/arriscan.html
This one uses a camera chip, but I guess it's so close to the film that you don't need a lens.

Resolution of film? Depends how you measure it. The results at an actual theatre:

The highest resolution that the expert assessors could still discern in the sharpest part of the screen (not
necessarily in its center) in the most performing movie theater was about 875 lines/PH.


The results of scanning a film negative

the MTF on the negative film drops to 10% of
its peak value at about 2100 lines/PH (lines per picture height).

I want to know that "all blu-ray are mastered with 24fps with Progressively or some tv show also with interlacing.

ya thats i am not understanding generaly quality seeking people take BD, then why "i" BD Produced.why not all progressive with 24fps or what any fps as that of original footage.

The original material was interlaced. So why not deinterlace it? I don't know right now.
