Fairly unsurprising news in and of itself, but, as SlashFilm points out, there is cause for optimism:
There’s reason to hope, too, that the Blu-ray release of Raiders of the Lost Ark will be the original release version, with no digital removal of minor ‘flaws’ like reflections of snakes in plexiglass. Last year, at an anniversary screening of Raiders, Steven Spielberg said,
This is the best I think it’s ever looked, because in preparation for the eventual release on blu-ray we had to correct the print again and get the original negative out of the salt mines, and then we had to do the separations, and basically the files, which are just amazing, with all the technology of today, without changing any of the movie materially, we haven’t removed anything, we haven’t added CGI, there’s no digital enhancements! It’s purely the movie you some of you may remember from 1981.
Only time will tell.
