Dr. Ekman and ‘Lie to Me’

Many of the episodes of ‘Lie to Me’ feature references from Dr. Ekman’s own experiences. The pilot episode shows the fictional character, Dr. Cal Lightman, lecturing to several FBI agents in a lecture hall. Dr. Ekman lectured to the FBI in a variety of settings, including lecture halls, throughout his career. Two FBI agents listening to Lightman’s lecture discuss the fact that Cal is reported to have traveled to the African jungle to study facial expressions in a primitive tribe. This reference is based on Dr. Ekman’s travels throughout the world to determine whether facial expressions are universal or culturally determined. Lightman shows the FBI agents a tape of his interview with a suspect accused of attempting to firebomb a church. Lightman focuses the agents’ attention on close-ups of the suspect’s face that reveal micro expressions of emotions the suspect is trying to conceal at different points in the interview – e.g., happy at one point, scornful at another point. One of the agents asks if micro expressions vary depending on the person, and Lightman responds by juxtaposing the still of the suspect’s micro expression of scorn with a close-up of the face of Kato Kaelin exhibiting the same micro expression of scorn. This portion of the pilot episode was based on Dr. Ekman’s scientific findings that micro expressions are universal.

The personal aspects of Lightman’s character, however, are not based on Dr. Ekman. For instance, Cal Lightman is young, divorced, British, and has a strained relationship with his one child, whereas Dr. Ekman has been happily married for over thirty years, and has a good relationship with his two children. Also, he’s American.
