I bought this guía de preguntas that I will use for class discussion. And I am also coming up with some of my own materials to use with the movie. We will definitely do a Seminario Socrático after watching this movie, because I think my students will have a lot to say about it. I particularly like this discussion question: Compara las perspectivas de la belleza de las canciones "Mantra" y "Soy yo" con las de la película "3 Bellezas."
The movie might not be appropriate for all ages, but I have juniors and seniors in my AP class so they will be fine with it. The movie is mostly appropriate (with one part at 47 minutes that I will definitely skip and maybe a couple of others). Here is the trailer:
This short video will be a good accompaniment.
