How True is a True Story?: Zodiac (2007)

Friday, 12 September 2025 - Movies “based on a true story” captivate audiences with the intrigue of history and the wonderment of how the film’s events could have transpired in real life. The reality is that these films love to blur the lines between fact and fiction in favour of cinematic storytelling. If you’ve ever found yourself wondering, “how much of this actually happened,” join The Confluence as we dig into the real events behind iconic films. In September, we're looking into the chilling unsolved mystery of the Zodiac Killer that inspired the 2007 movie starring Jake Gyllenhaal, Mark Ruffalo and Robert Downey Jr. In the late 1960s and early '70s, a serial killer known only as Zodiac taunted police and terrified the public—sending cryptic messages, threatening more deaths, and eluding capture at every turn. The killer's identity remains one of the most chilling unsolved mysteries in American history. - Event Details
