The final episode of the crime drama's second run will air on Fox on July 26. A 13-episode third season has already been commissioned.
"We have been talking about the third season already," Roth told TV Is My Pacifier. "I’m very close to the two guys that are running the show now, the two writers. We’ve been talking about what we would like and different ideas and so forth. I am meeting with them next week and they’re going to pitch stories to me and see what my feelings are."
The actor admitted that he enjoys playing his morally ambiguous character Dr Cal Lightman.
"I think what’s interesting about him is he operates in a [moral] grey area," he explained. "I have to say I like that about him. So I think we’re looking at developing the kind of rogue element of him even more in the third season."
Roth also revealed that he would like his lie-detecting role to face a criminal with similar abilities.
"[A character I want] is somebody that is way better than him at what he does. How do you deal with that? If you keep not being able to read them... and your face gets rubbed in it time and time again, how would he deal with that? I think [that] might be fun."
Lie To Me continues on Mondays at 8/7c on Fox.
