[Spoilers] Sir Harry Pearce

[lwhite53]

I think Peter Firth's extraordinary acting is what, for all intents and purposes, "made" the Harry Pearce character happen. HP was originally intended, I believe, as a minor character. But PF made such an impression in that small role that the writers just kept giving HP more and more script time.

The "spooks" come and go, but Harry is the core that holds them all together.
