the one with the flares inside the plane. It didn’t look like CG smoke/flare to me (you can normally spot the fumefx CG smoke by the motion being too fast and swishy, like with some of the CG explosions in places during the square fight) so actually filming that must have been super well-drilled and prepped because any fluffed action would be a pain in the arse to reset the scene, extract all the smoke then add the right amount in to the background etc. You don’t see stuff like that very often - and there’s was even a quite long sequence with locked off camera (ie without a bunch of edits and cuts interrupting the flow) so you can appreciate the use of the flare and smoke.

But what really made me lol at the insanity was the castle assault at the end where Ana De Armas’ character takes out the chopper then basically just charges right up the front driveway dodging sniper fire while launching grenades and destroying everything!
