The Brazilian National Curriculum Guidelines for Medical Schools highlight the important role of the humanities in medical training, aimed at establishing physician-patient relations based on care and respect for others. To achieve such objectives, students need the opportunity to learn bioethical concepts throughout their undergraduate medical training, in order for such concepts to serve as theoretical tools for decision-making on moral issues they will encounter in their professional careers. Among the possible strategies for teaching-learning in bioethics, cinema has emerged as an effective alternative because it recreates, on the screen, situations close to reality. These can spark emotions and thoughts capable of triggering reflection on moral issues and allow moral decisions, with students becoming used to the practice-theory-practice arc in problem-solving. This article presents thoughts on the pedagogical use of cinema to deal with issues related to bioethics during undergraduate medical education.
