Intro: This is WTTW, the Chicago television home of that intrepid Time Lord, Doctor Who. Tonight, The Good Doctor will encounter his oldest and deadliest enemy, The Taleks [sic]. And by the way, if you think The Doctor's assistant Romana looks a little bit different tonight, don't worry. You don't need to have your eyes checked. A new actress, Lalla Ward, has taken the place of Mary Tamm, who got trapped in a mysterious time warp while they were doing some location filming on the planet Atrios. That's showbiz.
