For eight seasons, Eric McCormack played jovial gay lawyer Will Truman on NBC's "Will & Grace," a man surrounded by voices competing for his attention: his neurotic roommate Grace, his flamboyantly peppy friend Jack and boozy socialite sidekick Karen. His latest TV role one-ups the babble: In TNT's new summer drama "Perception," McCormack stars as Dr. Daniel Pierce, a scruffy neuroscientist and professor who helps the federal government solve difficult cases with the help of his own multiple voices. He is, after all, paranoid schizophrenic.

McCormack also had a stint on Broadway, finishing up a role in Gore Vidal's "The Best Man." He also starred in another TNT drama, "Trust Me," set inside a present-day fictional advertising firm. But it was canceled after one season. The post-"Will & Grace" years -- TV-wise -- have otherwise largely consisted of a few Lifetime network ventures, including a short-lived comedy he produced called "Lovespring International" and guest-starring roles on network shows.
