A clip of PERCEPTION stars Rachel Leigh Cook and Eric McCormick has appeared, on You Tube, in which the two discuss their characters and the show. Some info can be gleaned from it, but Rachel speaks a little too soft at times.

In Perception, McCormack (Will And Grace) plays Dr. Daniel Pierce, a neuroscientist and professor recruited to help the federal government crack difficult cases. His intimate knowledge of human behavior and masterful understanding of the mind give him an extraordinary ability to read people, but his eccentric view of the world and less-than-stellar social skills can often interfere with his work. So this means that in addition to crime solving, we will get some humor. This clip mentions his condition so it appears he has some sort of illness (likely mental) that causes, at least partially, his odd behavior.
Rachel (She’s All That) co-stars as FBI agent Kate Moretti, Pierce’s former student and the person responsible for recruiting him to work for the government. Arjay Smith plays Max Lewicki, the teaching assistant whose primary job is to keep Pierce in line and on task. Kelly Rowan is Natalie Vincent, Pierce’s best friend and every bit his intellectual equal. In addition, award-winning actor LeVar Burton (Roots, Star Trek: The Next Generation) will play a recurring role as Paul Haley, a dean at the university.
