5. Canada
Throughout his career, Bond has visited more of the fifty American states than many Americans probably have, with his travels taking him to Florida, Kentucky, New York, Nevada, California and Louisiana. The northern neighbour of the United States, however, has never been officially graced with his presence, though it has doubled for other nations as a filming location. Canada is a former British colony and shares close cultural, economical and political ties with its former parent country. Despite being the second biggest country in the world, however, it contains just 33 million people, 30 million less than the much smaller UK. As a result of this, vast masses of the country remain untouched by humans, with Arctic tundra, large boreal forests, bays, mountains, waterfalls and huge lakes all contributing to the landscape. Any would make for a stunning action sequence backdrop (I can't be the only one who wants to see a fistfight between Bond and an adversary atop of the Rocky Mountaineer train or on the Maid of the Mist in Niagara Falls, right?), as would multicultural urban settlements such as Toronto, Montreal and Vancouver.
Example Scenario On a recreational visit to the country, Bond narrowly avoids an assassination attempt, going off the grid in a bid to ascertain who was responsible and why.
