The Informant!

Here is a zany and enjoyable movie based on fact. Mark Whitacre started out in the early ‘90s as a whistleblower to the FBI, trying to expose price-fixing by Archer-Daniels-Midland, the biggest of the Big Agribusiness juggernauts. However, he turns out to be bipolar, a compulsive liar, an embezzler, and frankly, a nut. It hardly matters that his original cause was just. He piles one lie upon another, all the while remaining an engaging and quite likeable character. He ends up in jail. Matt Damon extends his already considerable range playing Whitacre. Directed by Steven Soderbergh.
