How are they able to release older movies in 4k?

Were they shot in 4k or something we just didn’t have TV’s that could see 4k back in the day?

Film is an analogue medium, it has no resolution (though it does have grain, but that’s not the same thing).

If you still have the originals on film, all you need to do is digitally re-scan them at whatever new resolution you want, and optionally do any digital retouching to correct for damage or age.

If your original was shot digitally (which didn’t become the norm until this century) then you have to do some AI upscaling or something.
