But the California Cancer Registry said Monday it just finished three different studies that found the rate of cancer in Hinkley in recent years was nothing extraordinary.
The studies found that cancer rates remained unremarkable from 1988 to 2008.
Researchers said the 196 cases of cancer reported during the most recent survey of 1996 through 2008 were less than what would be expect based on demographics and the regional rate of cancer.
The award-winning film was inspired by the $333 million settlement by Pacific Gas & Electric with more than 600 Hinkley residents over chromium contamination.
Sick residents blamed the contaminated water for a variety of health problems, including cancer.
