TNT has renewed "Perception" for a second season, signaling a hit for the former star of the NBC comedy series "Will & Grace," Eric McCormack, reports the New York Post.

McCormack’s first try at a new series lasted only one season, with "Trust Me," a TNT series about an advertising firm.

In "Perception," which has averaged 7 million viewers since its premiere in July, McCormack plays a college professor who suffers from paranoid schizophrenia. His character works with a former student who is now an FBI agent to help solve crimes, the story adds.
