Reference hunt, such good sport, and NTTD certainly has a lot of them.
Which ones did you spot, which ones do you consider to be deliberate? Which one was nice and which one was unnecessary or plain stupid?
The soundtrack, of course, had the unmistakeable nods to OHMSS several times, but also to CR and maybe a few others here and there. Sadly missed (again): Barry’s 007 Theme, which was last heard in MR. A latin version during the Cuba fight scenes, perhaps…
DN references quite a lot, most notably the one at the beginning of the credits, but also the scientists’ lab outfits, and the grilled rooflights in Safin’s lair. The lair itself reminded a bit of Crab Key. Villains with an own island or lair at sea, anyhow, Spectre Island in FRWL, the DAF oil rig, Scaramanga’s island, and of course Silva’s Hashima island.
Cigar’s ashes on the steps of his house may actually be a reference to Sherlock Holmes, but in that universe, the cigar would certainly have been a Trichinopoly, instead of Felix’ Delectados.
One of which I’m not sure if it was intentional, but the death of Logan Ash reminded me a lot of FYEO’s Emile Leopold Locque.
What else did we have?
