To bad none of the movies that are on the 4k blu ray were actually shot in 4k. They were all shot 2k.

If shot in 35mm it is 4K. If shot in 70mm it was shot in 8K equivalent.

4K is the equivalent of 35mm 1.85:1 in resolution (give or take). Where as 70mm's frame is over twice the width of 35mm's and about double 1.85's height..it will take more than 8K to capture 65/70mm 5-perf and three times that for IMAX.

Don't forget the degradation that a 35mm original goes through, before the print gets projected in a multiplex projector.

Real 4K projected in a 4K digital cinema -- sadly -- is much sharper than most 35mm film projected in a multiplex, due to all the losses of the multiple steps (e.g. negative -> masters -> print)

Now....a flagship presentation in Chinese Mann Theatre, or one of the top-tier theatres.... That's a different story. Those really make sure the losses are minimal.

Thanks,
