Erin Brockovich is a powerful story about a lawyer’s investigation into the major cover-up of a local community’s contaminated water supply, earning its star Julia Roberts an Academy Award nomination for Best Actress in a Leading Role, but the film makes several changes to the true story of Erin Brockovich and her pursuit of justice. After landing a job at the same law firm that was handling her car accident case, Brockovich, a divorced single mother, discovered medical files hidden within real estate folders indicating extreme illness as a result of Hinkley’s drinking water contaminated by PG&E. Brockovich’s fight against the utility company made national headlines in the late ’90s.
