Is The Irrational New Tonight? (January 7, 2025)
It's never a dull work day for behavioral science expert Mercer on NBC's The Irrational.
Whether it's a high-stakes heist or a jaw-dropping murder scene, it's never a dull day for The Irrational's Dr. Alec Mercer, played by the captivating Jesse L. Martin.
The expert behavioral scientist has been hard at work as the twists and turns continue on The Irrational Season 2. Viewers have obsessed over the white-knuckled thrills of whatever intense case befalls Dr. Mercer and his team of behavioral wizards, with Martin delivering a dynamite performance while shining a light on the complexities of the human mind.
"We are so lucky and privileged to have Jesse Martin playing the role of Alec," showrunner Arika Lisanne Mittman told NBC Insider. "When I first wrote this character, there was a character I wrote on paper and there's what Jesse brought to it and those two things put together have just created magic and I'm so grateful to have him. He's wonderful to work with. He's really a gift to all of us."

"There are so many possibilities when it comes to just concentrating on how we think and how we behave," Martin told Collider. "Mental health is a big topic on everybody's platforms these days, and our show explores it, certainly in a scripted context, but in so many different ways with so many different people. The more interesting actors we get in, the more that behavior surfaces... There are so many places to get creative. There are so many stories that can get told when you're just talking about behavior, in general."
