Best known to Whovians as: Susan Foreman, the original companion who just happened to also be the granddaughter of the First Doctor.
Where she is now: For the most part, Ford stopped formal acting following an illness in 1977, but has continued to play Susan in a limited fashion in Doctor Who audio plays and companion stories. She'll appear in a small role as "Joyce" in the BBC America docudrama An Adventure in Space and Time, about the advent of Doctor Who
Fun fact: Claudia Grant will portray Ford in An Adventure in Space and Time
