Poll: Influential Films
"I created this poll based on academic research. Researchers at Northwestern University analyzed connections data on IMDb and found these 40 films had the greatest influence on future filmmakers. The authors of the research granted me permission to use their research in a poll. I gave them a link to the poll when the poll went live."
