: The official cast list for this movie is REALLY skimpy. I don't know if it's because it has a HUGE cast, or what...but even the actress Ione Sky (who has a recognized professional name, and a very visible supporting role as one of the Zodiac victims) isn't on it. So I don't know how an actual cast list would be assembled. What I'm saying is, the cast list that appears with the film is extremely sketchy, and doesn't really reflect the film. So someone has many sleepless nights ahead of them in compiling one...
