Throughout the history of film American filmmakers and International filmmakers have influenced each other. Let us start from the beginning. The first motion pictures were in essence from Nickelodeons, quite large machines (at least 4 feet tall), where one would insert a nickel (hence the name) and turn a crank which while turned rotated still image pictures that were illuminated from the back with lamps. As time went on, people began using this technique to make motion pictures. The first motion pictures were short films (about 20 seconds long) that were of various real life events (outside a train station, people lifting heavy items, etc.)
Shortly after there were comedic shorts that began to arise such as the famous boxing cats.
These shorts traveled to Europe and many European film makers began doing the same thing where they lived. It wasn't long after these shorts began that the film makers realized that these shorts were not what was going to make them money. Once a person saw one short, there was no need to return to see it again, so behold the introduction of short films with a plot, using film in a whole new way. The first to do so were the Lumiere brothers from France. Their first films were of everyday life in France (outside a train station, etc), and they are considered the fathers of modern motion picture. Their first short to introduce the idea of using a plot was La Voyage dans la Luna (A Voyage to the Moon). Although the acting style is much different to today's, and there is no sound, it is clear what the plot is, as well as all conventions entailing a storyline are used.
Throughout the history of film there have been many innovations introduced, the most important is editing. Although often overlooked by movie goers, editing is what makes or breaks a movie. If a movie flows well, and the audience can be absorbed into the movie without being reminded that they are watching a movie, then the editors have done their job well. But, if the editing is done horribly, no matter how good the plot, or how good the actors/actresses are the public will abstain and the movie will "flop." But, there have been cases where editing has been used "outside" the box and been successful. The first of these techniques were utilized in propaganda short movies, most notably the Russians and the Germans. These films traveled to the United States, and film makers took notice, trying it in films, unfortunately though it did not take hold for another twenty to thirty years.
Although films are influenced by other countries, they are also influenced by the regions that they are made. The region where movies are made are going to be made for the audience of that region, for example, European films tend to be a little more artsy whereas Japanese and American films seem to be more black and white, or epic. That is not to say that European films are lacking in these areas. Another example would be the Anime section of films, while taking hold in American film industries, they are viewed as "childish" and are recommended to children and not to adults, whereas this is not so in the Japanese culture, it is made for both adults and children alike. Most notably in the U.S. is Hayao Miyazaki who has teamed up with Disney to do such movies as "Howl's Moving Castle," "Ponyo," etc.
So, to say that one country's films are not influenced by another country's movies would be a farce. All films from different countries are influenced one way or another by each other, whether it be from the editing, to the way a movie's plot is done, etc.
