In the movie Zodiac, Robert Graysmith is played by veteran actor Jake Gyllenhaal, though Graysmith is very much a real person still alive today. His movie persona is shy and well-meaning though that doesn't stop him from being pulled into the absolute chaos that was the investigation into the Zodiac killer. Graysmith's costumes in the movie were typical clothing for the time: plaid button down dress shirts, slacks, and sensible work shoes. He also wore a blue puffy jacket in many scenes.

The key to his costume, however is in the details. You can get a copy of the code breaker book used to decipher some of the Zodiac's letters. And, if you're feeling brave, you can get some of the letters from the internet. They haven't all been deciphered and who knows? Maybe you'll be the one to crack the letters' codes while you're in Graysmith's frame of mind!
