If it's hard for you to believe that legendary TV funnyman Bob Newhart has never won an Emmy, don't worry: NCIS executive producer Gary Glasberg says he has trouble wrapping his head around that, too.The Bob Newhart Show and Newhart , guest-starred on NCIS last season as Dr. Walter Magnus, a former NCIS medical examiner who trained David McCallum's Ducky. "We came up with a list of actors that we thought that would be perfect for it," Glasberg says. "And then someone actually mentioned Bob. ... The role evolved and then turned into him. But initially, the thought was, 'Well, that'll never happen.'"Fortunately for the show, Newhart's wife is a huge fan. "They go out to dinner every Tuesday night with some friends. But they always have to get home in time to watch NCIS," Glasberg says with a laugh. "Sure enough, he read the script and responded to it. The rest was just as smooth and entertaining and wonderful as could be."But the role required some gravitas, too. Dr. Magnus' return was somewhat of a last hurrah, as the episode reveals that he's battling Alzheimer's disease. "My experience has been any time you can give a really talented comedic actor an opportunity to do some drama, they very often deliver," Glasberg says. "I knew that Bob had done some dramatic parts before, and we just sort of instinctually knew that this could work. This was an opportunity to see a different side of him and his real acting talent."Mark Harmon turning to me and saying, 'Bob Newhart needs to be recognized for this. This is really special," Glasberg says. "The man has had an extraordinary television career. This was a role that allowed us to see him in a different way. If in return NCIS can give him some recognition through an Emmy nomination, we would be honored and thrilled to be able to provide that."Do you think Newhart's NCIS performance was Emmy worthy?
