Problems began when the FBI got ahold of the screenplay. Robert Evans claims he was visited by FBI Special Agents who didn’t appreciate their unflattering and incompetent portrayal in the film. When Evans denied their request to cease production, they began conducting surveillance on the film’s set. Evans refused their demands, but increasing pressure led to extensive overdubs during the film’s post-production phase: the FBI became the FBR, and the CIA became the CEA. Even the Telephone Company got wind of their negative portrayal in the film, and Evans believed that his telephone had begun to be monitored by either the Bureau or the phone company. Evans’ paranoia would ironically mirror that of James Coburn’s character in the film’s storyline.
