Did You Know?
Walker had been cast in 1973 for the role of Sarah Jane Smith in Doctor Who
(1963), but her participation was vetoed by the incumbent Doctor at the time, Jon Pertwee
, who felt that she didn't fit the role of a companion well, and there was a distinct lack of chemistry between the two. The role was recast with Elisabeth Sladen
portraying the character.
