Sky’s version is not the open matte version unfortunately, was also disappointed they didn’t get Spectre in open matte either like they did with SkyFall, hopefully ITV will when they show it (with logo though) as they’ve shown all previous Daniel Craig Bond’s open matte.
“Spectre” was shot primarily in anamorphic 35mm, with some digital and Super 35. http://the007dossier.com/007dossier/post/2016/01/02/Capturing-007s-Icy-Cool-in-Spectre has the AC article but haven’t re-read it so I don’t remember how specific they get regarding scenes they did non-anamorphically.
