Teaching in Person?

Section 110(1) of US Copyright Law permits the performance and display of legally licensed/purchased works protected by copyright for education purposes in nonprofit educational institutions. 

17 USC 110(1)

(1) performance or display of a work by instructors or pupils in the course of face-to-face teaching activities of a nonprofit educational institution, in a classroom or similar place devoted to instruction, unless, in the case of a motion picture or other audiovisual work, the performance, or the display of individual images, is given by means of a copy that was not lawfully made under this title, and that the person responsible for the performance knew or had reason to believe was not lawfully made;

If a movie has an instructional purpose related to the course and it's only being shown to students enrolled in the course instructors in a face-to-face class may use content appropriately.

NOTE:

1. This does mean that the content must be legally obtained, lawfully made (no-ripped content), and used in accordance with any licensing terms that may apply from the content vendor. 
2. This exception applies only to the showing of films in physical classrooms not remote locations and limits the audience only to instructors and students in the non-profit education setting.
