The thesis ?Effeminate Gay Men in U.S. Film? portrays and connects different aspects of masculinity, femininity, homosexuality and film theory in the U.S. In the first half, the thesis deals with the great influence of hegemonic masculinity in Western society and its meanings. Its purpose is to show that there are unequal power relations between men and women that cannot be denied. Patriarchy, as a system oppressing not only women but all groups that are not part of hegemonic masculinity, such as homosexual men, is discussed in detail. The subgroup of effeminate homosexual men, which is of main focus in the analysis, is socially lowered through their status as being feminine. Foucault?s theory of the Panopticon will be used to explain how the patriarchal system and the disparagement of everything connected to femininity is already part of people?s unconsciousness and does not have to be forced on anybody. There are norms and sets of behavior expected from all members of Western society which entail that heterosexual hegemonic masculinity is the accepted form of power in society which should be lived up to in order to be an accepted part of society. This mindset is one of the main reasons why women and effeminate gay men are subordinated to heterosexual men. Film, as the medium used for this analysis, is one way to support patriarchal power relations and to maintain a conservative image of society. Mainstream films tend to represent a picture of society in which patriarchal structures are emphasized and advertized to the spectator. Frequently, film portrays role models of social sex roles typically assigned to males and females. For the analysis, several scenes of Brokeback Mountain (2006), Shortbus (2006), The Rules of Attraction (2002) and The Birdcage (1996) have been chosen. The scenes have been selected in respect to effeminacy in male homosexual characters. Masculine and feminine behavior in heterosexual and homosexual men will be contrasted.
