Moonraker - the 2 guys who die from radiation in that science lab, but when James Bond goes to it, it's not a science lab any more.
The World Is Not Enough - that Philishave look-alike weapon that sinks a big ship at the beginning of the film. Scary stuff.
Live And Let Die - Bond driving a double-decker under a bridge and tears the top deck off
You Only Live Twice - the volcano base being invaded by ninjas and the lid being blown off by a bomb.
The Man With The Golden Gun - the fat angry American copper. He was ace! Think he was in Live And Let Die too.
Goldeneye - the Bond girl who kills people when she has sex with them. I never figured out how she kills them.
Skyfall - the train getting derailed and crashing through multiple floors.
