<< Personally, watching movie is one of my hobby and therefore, I know its fascination and some points of popularity. The reason why movie is so popular is, I guess film provides audience with the fun of taking part in the film's story, which let us seem to experience many interesting things in the story. Then in order to prudece attractive film works enough to involve people in its story, film makers use some devices. Realistic or amazing set is important key to produce good film. When popular films are shooted, advanced machines like camera are used and techniques like CG make each scene realistic one. In fact, in one of the most famous and popular film, �gTITANIC�h, I heard that film producers made good use of computer graphics and prepared dead people falling into sea only by CG technique without which they could have not shoot such realistic scenes . Effective use of such advanced technology enables film makers to shoot some scenes of actions that living people could not do. Film cast is also important factor of film's popularity. It is because experienced actors perform every action in the film very natural so that we can be involved in the story easily. Actors and actress are usually very beautiful and therefore we sometimes want to go movie theater only to watch such celebrities. Anyway, looking at such people itself is one of our fun in watching movies. Last but not least, film music is fascinating. The music, compused by make each scene effective, also enhances the films' atmosphere and help audience concentrate on the story. Film music itself is well-composed and attract us. Actually my friends said that they sometimes felt content only to hear wonderful music in front of screen, even if its plot seemed to be devastating. From my analysis of film's popularity, these points, effective setting, casts, and music is the reason why people go to watch movie. These devises really help audience to enjoy themselves in the film's world escaping from their own reality
