I'm opening a new thread for the new series Lie To Me starring Tim Roth.
Here's the Wiki entry for the show:
Lie To Me is an American television series that premiered on the Fox television network on January 21, 2009. The main character, Dr. Cal Lightman (played by Tim Roth), detects deception by observing body language, and uses this talent to assist law enforcement with the help of his group of researchers and psychologists. The character is based on Paul Ekman, notable psychologist and expert on body language and facial expressions. This show is similar to Lifetime's Angela's Eyes.
Two episodes have already been aired and it's pretty good. Tim Roth is da man, and the stories are quite compelling.
