I did just find open matte copies of Spider-man 2 and 3 online, sort of. They’re not open matte in the same way as the first one. They’re 16:9 and look like studio transfers rather than an enthusiast 35mm scan, and they’re highly compressed. It does have more image area than the 2.39 film scan, though (at least on the shots I checked).
sir i want the copy of spider man 2002 35mm
