She's too big. A star, after all, needs to maintain a certain distance between herself and ordinary people. Once Erin has humiliated every healthy woman in Southern California, Erin Brockovich can come to a close. Virtually all illnesses are caused by some sort of corporate wrongdoing. The best way for people to get even with big corporations is through class-action lawsuits.
Trial lawyers deserve the huge fees they earn in class-action suits.
So that, far from telling a true story, Erin Brockovich deliberately tells a false one. If it puts a smile on Julia Roberts' face, it's worth it. Okay, Paula Jones on a great hair day. If this movie has been shown at the White House, and I bet it has, more than once, there must be claw marks on the screening-room walls. In typical Hollywood fashion, we see that the accident is clearly the other guy's fault, but the jury decides against Erin, even though the guy that hit her is rich and she's broke.
