Disability - Murderball
Work - Office Space (also for Bureaucracy), The Apartment
Research Methods - Something the Lord Made, Madame Curie
Religion - Agnes of God, The Magdalene Sisters, Keeping the Faith (Edward Norton comedy)
Mass Media - Ace in the Hole (Billy Wilder)
For Social Interaction, the two that leap to mind right away are:
Fast Times at Ridgmont High
Legally Blonde
Both of them have that "this is what's done," fitting into a social strata vibe.
For Social Interaction - Heathers.
I guess it would also fit under Crime and Deviance.
How about Dogma for Religion?
Social Stratification- Howard's End.
These are all great suggestions--keep 'em coming!
Oh, hell -- for religion, look no further than Jesus Camp.
Also my personal favorite, Saved.
Mass Media -- Good Night and Good Luck.
Social stratification - Pride & Prejudice.
Work - Office space
