One of the qualities my family and I loved about Doctor Who was the stage like feel the show gave. The paperclips, the tinfoil never bothered us, but would easily ruin other shows. As I understand, Vaudeville was a major part of the early doctors like Troughton. Troughton brought a lot of humor and slapstick coupled with his crazy faces and often tinkering with objects while talking.
What I am curious to know is how much of your character was scripted, and how much off the cuff. And, if you don't mind, how much some of the other doctor's ad libbed, or did not. It always struck me that there was a lot and that the dialogue always flowed so smoothly and naturally between the Doctor and his companions
Thank you for your time.
