LGBT cinema in Latin America: Queer individuals' contradiction of the heterosexual norm significantly impacts the machismo ideals within the Latin American culture, where men are expected to be strong and dominant.

While many have attempted to bring the Latino transgender man into queer cinema, such as in Arturo Ripstein’s "El Lugar sin limites" (1978), the man is seldom portrayed in a positive light.
