"Dietzen says his character's relationship with mentor Ducky is similar
to his with McCallum in real life. "I get to go to work every day and work
with a TV acting legend," Dietzen says. "We have some great guest
stars on the show like Robert Wagner and Ralph Waite. ... It's great to meet
these folks, but I never lose sight of the fact that I get to do it every day
I go to work. There's a lot that's translated into the characters. Jimmy's always
learning from Ducky, and I am constantly learning from David.""
