This experimental study explored how audiences perceive AI-generated film screenplays compared to those written by humans. Using a 2×2 factorial design, participants evaluated screenplay excerpts created by ChatGPT under varying conditions of authorship and film festival accolades. I led the research design, data collection, and statistical analysis, utilizing SPSS and mediation testing. Results revealed that authorship alone had no significant effect on screenplay interest or emotional connection, however, screenplays without accolades garnered higher interest than those with accolades, challenging assumptions about credibility signals in entertainment. Among those who read AI-generated content, higher interest significantly correlated with intent to stream or purchase the full production. These findings provide insight into the evolving role of AI in creative fields and suggest that consumers may judge content quality independently of authorship or prestige markers.
