Created by Samuel Baum, Lie to Me, is a crime drama featuring Tim Roth, Kellie Williams, Monica Raymund, and others. The show aired on Fox from 2009 to 2011 for three seasons and focuses on Dr. Cal Lightman (Roth), who with his colleagues in The Lightman Group, accepts assignments from other federal law enforcements and assists in criminal investigations.
Lie to Me is unique as Cal and his assistants work on cases with the help of applied psychology, interpreting micro expressions, and body language. Psychology therefore forms a core component in the show. Lie to Me is inspired by the work of Paul Ekman, who specializes in facial expressions.
Ekman has worked with several police departments and anti-terrorism groups and was a scientific consultant for the show. Therefore, the character of Cal is based on Ekman.
