So it's only 4k if it uses an aspect ratio close to 4:3 that covers the whole film? And the film won't have a horizontal resolution equivelant to around 3840? The resolution is still much higher than 1080p and closer to 4k and I've heard that it can vary throughout a film, so wouldn't it still benefit from being remastered at that resolution? I've also heard that any IMAX film will have more quality than 4k.

The theoretical maximum for fine-grained 35mm film is about 8700*5800 pixels or about 50 Megapixels. So regardless of aspect ratio, any 35nm film could be scanned to better than 4k resolution (whether you want/can do that or not depends on your budget and film quality).

Nobody actually has reached that theoretcal maximum.. there are limits because of equipement, lenses, film grain quailty and the time you can actually stand still for a few minutes to capture at that detail... it's impossible on 35mm to reach that... especially in movies.. even the best could only reach around 4k full frame.. that's why it's theoretical...
