He's one of the most famous characters in film history and over three billion people have watched him -that's half the world's population! Since 1962 he's been in twenty films, or one film every two years. Who is he? He's Bond ... James Bond.
The British writer, Ian Fleming, created James Bond in 1953. Fleming was a typical English 'gentleman'. He was educated at Eton (an expensive school in England), then worked as a journalist before becoming a banker in London. However, during the war his life completely changed when he worked as a spy in Russia. He wrote most of his novels about his own interesting experiences.
Although the Bond novels were exciting action stories about spies, they didn't become well known until they were made into films. When the first film Or No opened in Britain in 1962, Fleming became famous overnight. However, it wasn't untilGoldfinger in 1964 that James Bond became successful around the world. Goldfinger broke box office records at home and abroad. The phrase `I'm Bond ... James Bond' was recognised all over the world.
Will Bond films continue to entertain us in the future? The answer is probably 'yes'. There will always be James Bond fans because audiences will always enjoy exciting thrillers. The last film, The World Is Not Enough, made an amazing £6.2 million in its first weekend! The truth is that James Bond films, with their fast cars, spy gadgets and dangerous missions, are the ultimate action movies.
