I think Jon Pertwee was the Dr. who was very Edwardian in his dress. Did you ever see any of the Cadfael videos on PBS with Derek Jacobi as the Benedictine Monk? Sean Pertwee, Jon's son, played the Sheriff in a few of those adaptations.
Yeah, I've seen Robert Hardy in a number of movies over the years, and it still throws me off - I always think of him as Siegfried.
The Dr. Who I'm thinking of usually had shirts with kinda frilly colors and sleeves. Is that what you mean by Edwardian?
Oh, and yeah, I've seen a few of the Cadfael shows.
