The group chose to research the crime thriller film Zodiac (2007) as their example. Zodiac is about a real serial killer who stalked victims in the 1960s-70s and taunted investigators with cryptic messages. They felt it followed genre conventions well to inspire their own teaser trailer and poster. Their analysis found the teaser trailer used fast editing, closeups, fades, and mysterious text and imagery typical of thrillers. The film poster also used common thriller elements like a night setting, low-key lighting, the characters' faces, and colors of black, red and blue that connote fear, blood and the police investigation.
