Erin Brockovich (2000)
This movie makes the list even though it addresses cancer indirectly. Julia Roberts won an Oscar for her performance as a brassy woman who lands a legal job and starts digging into the case of a company that has contaminated land with toxic waste that might be causing serious illness in a community. It’s based on the real-life Erin Brockovich, who won one of the biggest class-action lawsuits in American history.
