Ask your teacher....then it would have to be something that is approved by your school board to be watched in your district. Usually age appropriate. It would have to deal with a subject you are learning about in order to view the whole film. However, if you show just a few minutes that can sometimes drive home the example just as well if you find small clips. If you make the movie that is one thing...if you just show a movie someone else has made, that is something else.
