Very similar themes and plot and ideas of Snowpiercer!
Saw High-Rise last night and kept thinking how similar it is to Snowpiercer...
The people are stuck in their environments; they despise the inequality between the classes, and want get to a higher floor (or, in Snowpeircer, the front of the train).
Replace sex in High-Rise with shooting/punching as the preferred mode of self expression in Snowpiercer.
While the setting of a building/city is more plausible than the train ecosystem, I connected more with the snowpeircer story, and enjoyed it more than high-rise, despite excellent performances by Hiddleston, Irons, and the rest of the cast.
