Continuity mistake: When Cal goes to tell Mr. Dawkins that his daughter has HIV, he brings a glass of water into the room with him. The glass is half full (or half empty, depending on how you look at it), but throughout the scene it keeps switching between half full/half empty and three quarters full/one quarter full.
Lie to Me (2009)
1 continuity mistake in Darkness and Light
Starring: Tim Roth, Kelli Williams, Monica Raymund, Brendan Hines
Visible crew/equipment: At about 30 minutes into the episode, right after Cal says: "if Jeffrey knows about priox, he's going to jail. But I'm gonna be damn sure before I send him there", you can see a hand in the top right corner of the screen.
