I am a High School Physics teacher and I own a legal copy of The Martian. The kids keep asking about the movie because I mention it a lot in class to give examples because a lot of topics that we are talking about are discussed in the movie. Current copyright and fair use laws have been quite confusing for me and I was wondering if anybody here is familiar with them. If I were to show the movie in class to my Physics kids with a legal copy of the movie, will the violate fair use laws? Thank you!
