Review of Koroshi

When I saw this two part episode of secret agent John Drake, I was amazed. It was in color and besides the cool and inteligent British secret agent was running and fighting like he never did before. I enjoyed this T.V. show. Then one or two years later the film You Only Live Twice was released in Mexico city and I was there the very first day. I`m a James Bond fan and I wouldn`t miss a 007 movie for anything in the world, but as I was watching the movie I had a surprise, the plot was very much alike that John Drake episode I have seen years before. The Japaneses, the island, the secret base, a character named Tanaka... What happened here? Is it possible that a James Bond film has taken the same idea from a good T.V. show? Who stole who? Can anyone make it clear to me?
