As a general rule, no. I find it difficult to believe that most Hollywood movies R-rated or not would be relevant to the curriculum. Other than movies relevant to the curriculum I can't see why they'd be shown. Of the three movies mentioned: The Matrix, Saving Private Ryan and Boiler Room, the only one I could see as being relevant would be Saving Private Ryan if you had a lazy-assed athletic coach as a history teacher.
Boiler Room was in Economics.
Why the sh*t would a teacher show
Boiler Room in an econ class??
I agree completely with Emsworth and Ernest-- what educational purpose do Hollywood movies serve, if not crude indoctrination?
