Silkwood is a 1983 American biographical drama film directed by Mike Nichols starring Meryl Streep, Cher and Kurt Russell.
 The screenplay by Nora Ephron and Alice Arlen was inspired by the life of Karen Silkwood.
 Silkwood was a nuclear whistleblower and a labor union activist who died in a suspicious car accident while investigating alleged wrongdoing at the Kerr-McGee plutonium plant where she worked.
 In real life, her death was vindicated in a victorious 1979 lawsuit, "Silkwood v. Kerr-McGee", led by attorney Gerry Spence.
 The jury rendered its verdict of $10 million in damages to be paid to the Silkwood estate (her children), the largest amount in damages ever awarded for that kind of case at the time.
 The Silkwood estate eventually settled for $1.3 million.
