This document discusses key concepts related to science fiction film audiences: 1) Films can target different audience segments defined by demographics (age, gender, etc.) or psychographics (attitudes and values). The "target audience" is the intended segment. 2) Some films appeal broadly ("mainstream") while others attract a smaller group ("niche"). 3) Audience research involves understanding demographics and psychographics to design films that fulfill viewers' needs like entertainment, information, identity, and companionship (uses and gratifications theory). 4) Films offer "utopian solutions" that compensate for real-life lacks like intensity, energy, transparency, community, and abundance.
