Bond's final battle against Sanchez, leading to Bond using Felix's present - a lighter - to set a gasoline-soaked Sanchez on fire, giving him a quite Karmic Death.
Timothy Dalton deserves a nod in regards to that scene for not using a stunt double for when Bond is running from the explosion. In more than one interview around the time the movie came out, Dalton said he was practically running for his life.
The scene at the Hemingway House where M appears in person to order 007 to leave Sanchez to the Americans. Previous stories had Bond considering leaving the service in disgust. This time...
Bond: SIR! They're not going to DO ANYTHING! (beat) I owe it to Leiter. He's put his life on the line for me many times. M: Oh spare me this sentimental RUBBISH! He knew the risks. Bond: And his wife? M: This private vendetta of yours could easily compromise Her Majesty's government. You have an assignment, and I expect you to carry it out objectively and professionally! Bond (with suppressed rage): Then you have my resignation, sir! M (angry): We're not a country club, 007! (beat) Effective immediately. Your licence to kill is revoked...
You know that scene in The Dark Knight Rises where a plane is yanked from the sky and pulled by another larger plane? This movie did it first, but with a helicopter pulling a plane.
The crowner is Felix and James parachuting down directly down to Felix's wedding - leading to a wedding where the groom's outfit has a train and the bride's does not.
Bond sees a bunch of Sanchez's goons coming up to his yacht with the corpse of Bond's ally, Sharkey, one joking about having the guy hung up like a fish. Instead of a clean escape, Bond takes the time to grab a spear gun, tell the killer "Compliments of Sharkey" and nail the guy as payback. As the movie illustrates, never screw with Bond's friends.
Bond, underwater, harpoons the pontoon of a seaplane, rises to the surface, skis until he's alongside it, climbs into it when it's in the air, and throws the pilots out. All this and escaping with the laundered cash in it.
Q coming to a Banana Republic in order to aid 007 and chucking an invention away once he'd done with it.
Plus, this is the only film aside from Octopussy, Skyfall, and Spectre in which Q actually has a sizable role, instead of just showing up at the beginning to give Bond his gadgets.
The signature gun all by itself is made of this. The reaction of the ninjas when they are unable to use it against Bond is priceless.
