Help again!!!!

MrPedantic, Mister Micawber or anyone else willing to help:

I wrote another essay. This one is for the the supplemental application for Chapman University's film school. The topic is: the most influential film.

Could you please read it, and tell me how I can improve it, and if there's any spelling or grammatical mistake.

Here it goes:

Most Influential Film

The Matrix:
What is the film that has influenced me the most? That’s not an easy question, since I usually learn something new from every movie I watch. However, The Matrix is the film that influenced me to want to become a film director. Therefore, that’s the one that should receive the biggest credit. It wasn’t actually the story that influenced me, but the making of the film.

When I came to the United States, I didn’t know any English. To be sincere, I wouldn’t even go to the Seven Eleven near my home to buy milk because I was afraid that someone would talk to me, and I wouldn’t know what to say. As a result, my mom suggested that I should watch lots of movies in order to get familiar with the language. By the time, I started watching TV with subtitles, in order to read and understand better what I was watching. I stayed at home for six months just watching TV as I waited for the next high school year to begin. Then, my mom decided to buy DVDs because she was told that they had better resolution than videos.

One of the first DVDs that we bought was The Matrix, which I liked very much. Then, I noticed that the DVD had special features, which included the making of the film. After having watched the movie numerous times, I thought that it would be very interesting to see how it was made. After I finished, I was amazed at how much work was put into making the film, and I realized that most people don’t know that. Also, I realized that there’s more to a film than having a good time watching the life of fictitious characters, and seeing how they go through changes and struggle to solve a problem or accomplish a goal. In fact, the one and a half to two hours that it takes a viewer to watch a movie are equivalent to numerous hours of work from its makers. Later on, I learned that with every movie it is the same. Some of them don’t need a great number of special effects, but they require a lot of work too. Thanks to that, now I appreciate movies much more than before. I didn’t know that a blue or green screen is used to make special effects or to change the background and make viewers believe that the actors are in a certain place when they are actually in a studio. Before, I used to wonder why would the makers of a film even bothered adding those long credits at the end if most people don’t care to watch them. Now, I understand that every person listed on the credits is indispensable for the film because every one of them did something to make the it unique.

I used to think that I wanted become a biochemist before I watched The Matrix. Then, I realized that there is nothing I like more than watching movies, and to see how they are made. Now, every time my family buys or rents a DVD, I watch the special features that come on it, thinking that one day I will become a great film director, and be able to participate and to play an important role in the making of films. Even though, it wasn’t the movie itself the one that actually influenced me, the fact that I liked the story and the special effects drove me to want to watch the making of the film, and decide that I wish to become a film director.

Thanks partly to The Matrix and mostly to its DVD, which enabled me to see what was behind the film, I learned to appreciate the work of everyone who was involved to bring life to its story. The film not only helped me realize all the work that it is put into the making of a film, but it also helped me to decide what I want to do with my life, which is to some day become a great film director.
