In the strong professional and career-centric atmosphere here at Cornell University, one piece of wisdom has become common knowledge: first impressions matter. Anyone who’s walked into career services, trained for interviews or opened a self-help book on the topic can tell you that. First impressions are important for impressing those internship recruiters, and also for winning over audiences. Hundreds of films come out every year; every single one has to sell itself to us. Their first impressions matter so very much, and they usually come in the form of teaser trailers.
