I don't know if youv'e read Mr.Graysmith's book-but if you have, I would also recommmend his follow- up, written after major Zodiac suspect Arthur Leigh Allen died. It's called ZODIAC UNMASKED. Allen was just about to be indited for the killings when he keeled over...an apparent natureal death. Fascinating reading!!!
On a different note...in 1970, an expliotation film was made at the height of the killings...called the ZODIAC KILLER. Very low budget-and in no way close to the facts. The police used it to try and trap the real Zodiac...hoping he would want to see the movie himself.
the first ZODIAC KILLER movie...
I remember seeing this on a uhf channel in the late 70's. A bizzare movie!
Loved the new one! I too was amazed to how close to the facts it stayed. For once, a docudrama that did'nt play with the facts.
