I use the movie "An American Tail" in my American Studies class to wrap uo our discussion of Ellis Island, and immigration in the late 1800s/early 1900s. Although it is a cartoon my juniors always love it. It is a surprisingly accurate portrayal of the immigrant experience, and the fact that it depicts mice vs. cats is a great exercise in media literacy. There is a lot of symbolism to decipher. It is about 85 minutes long. I have proved the study guide answer key here. For the students, you need only delete my answers and pass it out to them to take notes on during the film. Of course it can also be used for younger students. There are a total of 16 questions, with answers provided.
