Among all films I have ever seen, I like the movie called Kingsman – The Secret Service. It is a great and wonderful movie. In this film, You can see the wild spy action adventure director Matthew Vaughn has made up, based on the same name comic of Mark Millar. And it sounds like Vaughn already has some big ideas for the sequel. Based upon the Mark Millar’s comic book, Kingsman: The Secret Service will tell the story of a special super-secret spy organization that recruits an unrefined but promising street boy into the ultra-competitive training program of the agency just like a global threat emerges from the special twisted tech genius. If you do not want to loose the best time with the interesting action, you have to turn on your TV and watch Kingsman: The Secret Serivce now.
