Cal Lightman (played by Tim Roth) is a protagonist in Lie to Me.
Lead researcher and team head who uses an academic approach to micro-expressions and deception detection. He is driven by guilt over his mother's suicide and employs psychological tactics, careful questioning, and theatrics during interrogations rather than force.

Newly hired TSA officer and associate who scores extraordinarily high on Cal's deception-detection diagnostic, earning the label of a natural. Her intuitive talent often clashes with Cal's academic methods, and she frequently quotes his books during conversations. Eli Loker (played by Brendan Hines) appears in Lie to Me.
Founding team member who initially partners with Foster to investigate separate cases before the team structure evolves to have all four members collaborate on a single case per episode. Emily Lightman (played by Hayley McFarland) appears in Lie to Me.
Zoe Landau (played by Jennifer Beals) appears in Lie to Me.
