A fictionalized account of a true story, it centers on the controversial 60 Minutes segment about Jeffrey Wigand, a whistleblower in the tobacco industry,[3] covering his and CBS producer Lowell Bergman's struggles as they defend his testimony against efforts to discredit and suppress it by CBS and Wigand's former employer.

Though not a box office success, The Insider received acclaim from critics, who praised Crowe's portrayal of Wigand and Mann's direction. It was nominated for seven Academy Awards, including Best Picture and Best Actor in a Leading Role (for Russell Crowe).
