Trivia / Dr. Quinn, Medicine Woman
Dawson Casting: Jane Seymour was 42 when she began playing the role, but Dr. Mike is established as being in her mid-30's.
Executive Meddling: The darker tone during the last season is said to have been in response to the network not liking that the show's primary demographics had fallen out of the coveted 18-40 range.
Jane Seymour is British. In fact, she used to be a Bond Girl. It's not exactly clear whether Quinn's accent is supposed to be some version of upper-class Bostonian; her family talks roughly the same way.
