I've seen Oppenheimer and Dune 2 (I did the former on my flight back to Hong Kong, actually). Have heard good things about Monkey Man but I'll see bout the rest
Obviously LOTR, but if you have not watched these....Godzilla Minus One, that Louis Koo slums movie, BSG (start with the miniseries if you can download it), Shogun, The Acolyte (if you care for Star Wars)...
You're probably too young but the City Hunter remake on Netflix is very much on point with the series, a bit sanitized but on point.
I ended up watching Bluey when I flew Emirates for 13 hours though and nothing else lol
I do an extended version rewatch every two years or so when there is absolutely nothing on. It boggles my mind still it was twenty years ago they came out and the fx is better than some movies today (even the tv series).
