After the movie "All The President's Men" was a hit, interest in journalism schools increased. "LA Law" debuted on TV, law school admissions went up. After "ER," the same thing happened for medical schools. "Silence Of The Lambs" created an interest in people who wanted to be criminal profilers. "CSI" created a boon in crime scene investigator wannabes. Similarly, the Fox series "Lie To Me" started a wave of fascination with the ability to tell whether someone's being honest just by reading their faces and bodies. But, says ex-FBI agent Joe Navarro (himself an expert in non-verbal tells), it's not as easy as Tim Roth makes it look.
