There are many cinematic and documentary movies about mathematics and mathematicians in every field of mathematics. Particularly in logic, set theory and philosophy of mathematics, which are my research fields one can find plenty of such interesting movies easily. These movies explain complicated technical mathematical and philosophical ideas in a simple language. Also they can introduce the historical development of the subject and show the mathematical and non-mathematical aspects of the life of the professional mathematicians.
I have an idea to use these movies for motivating undergraduate students for doing simple new researches in the scientific aspects of the movie during the semester and give a lecture about the results at the end but I am hesitated about the possible positive or negative aspects of such a teaching idea.
Is it a good idea to use movies for motivating undergraduate students? In the other words, what kind of benefits and harms such an idea can have? and, how should a teacher use these movies to have maximum benefits and less harms? Are these movies useful for graduate students too?
