DCI 4K (4096x2160, very similar to consumer 4K) has been the standard resolution for digital intermediaries in the film industry for a couple decades now. Due to the popularity of digital compositing and color grading, that's going to be the maximum effective resolution of any major film made in the last 15 years or so. ("O Brother, Where Art Thou?" from 2000 was the first digitally color-graded film, and IIRC this also makes it the first live-action film where every single frame was digitized.)
