Zodiac (2007)
Featuring Robert Downey Jr., Mark Ruffalo, Jake Gyllenhaal, and Anthony Edwards, there’s no doubt about the fact that Zodiac offers an impressive cast. What you might not realize, though, is that this mystery-thriller is actually based on a true story – which means that the chilling events that took place during the 1960s in San Francisco really happened. The Zodiac killer was waging war on the people who lived in the surrounding area, and it was down to these guys to try and track him down and put an end to the devastation raging around them.
