"Lots of places have a Nooooorth!". First episode on the first (recent) series, and I still remember that one line. In fact, most of the memorable lines are Eccleston's. I especially like it when he told off the Gas Mask kids in the WW2 one.

Not poo pooing David Tennant or anything. He's a fantastic actor. When Rose "died", his face actually looked like the face of a 900 year old Time Lord who had lost yet another companion and was setting himself up to being alone again. Ruddy brilliant.
