Are we talking about Mark Whitacre? He was a piece of work. His whistleblowing was legitimate but the massive embezzlement was also legitimate.

The Soderbergh film The Informant! starring Matt Damen is about that story.

Yeah that movie is almost completely unwatchable though. They took this conspiracy story and tried to make it into a zany slapstick comedy. I have no idea what Soderbergh was thinking.
