I always loved Roger Moore but he was no one's idea of a stone cold killer.
My 2 favourites are Thunderball and You Only Live Twice. Brilliantly evocative the underwater battle filmed in th Bahamas is just great. Love Adolfo Celi as Largo, especially wearing a tux with wet suit leggings!
The Japanese location work on the other one is terrific and what self respecting super villain wouldn't have a hollowed out volcano as his lair. Without this, there's no Austin Powers!
Both films with epic soundtracks too.
No time to die is all about Daniel Craig but not a Bond film.
