this movie be obviously low budget and film in british columbia and canada . the obstacle that have to be overcome to make this movie convincing ( set in california and late 60 80 ) be well conceive . i believe this be the best and most accurate version of the zodiac killing that plague the town of vallejo and the bay area from 1968 19 . ( he be never catch ) . edward james olmos ( det . dave toschi ) and george dzundza ( zodiac at the time believe to be arthur leigh allen and since clear by dna and fingerprint ) play a game of cat and mouse re visit crime scene together and each one try to trigger the other into an emotional revelation . olmos die from some type of terminal disease and know dzundza do it and still totally obsess to the point of lose his family and become a full blown alcoholic along the way . dzundza totally oblivious and self absorb ( like all serial killer ) to the carnage leave in his wake . the only disappointment be theover the top end otherwise pretty accurate . if you tire of the typical hollywood fluff or have an interest in the zodiac case and check it out .
