labour theory from a movie

Students will write a one-page essay proposal. The proposal will include a proper bibliography that contains at least 6 academic sources.
Students will write an essay that critically analyzes a film, a series of films, or film theory through the lens of social class. Our concern in this course is with the working class and its interests, and essays should reflect this focus. Students may write about a film or films not included in the course syllabus, so long as the themes of your essay fit with those of the course. Essays will be 12 pages in length (excluding references), double-spaced, written in Times New Roman font, size 12, with reasonable margins (no funny business). Theres no need for a title page.
