A seminal essay to start with might be Louis Althusser's "Ideology and Ideological State Apparatuses" in the collection of his essays entitled, LENIN AND PHILOSOPHY. Sketches a theory of how cultural institutions produce systems of meaning which "interpellate" individuals. Not specifically about cinema but relevant to the degree that one considers the institution of cinema as an ideological state apparatus. Very influential to film theory of the past 30 years. ---- Online resources for film/TV studies may be found at ScreenSite http://www.tcf.ua.edu/screensite
