Never mind the gender, feel the height
Past doctors have been tall by the standards of leading men (cf T. Cruise Esq. and similar midgets), so we might have expected a tallish woman for the part. JW is only average at a non-metric 5'5", which is going to make setting up face-to-face confrontations with villains a whole new ballgame, as we say here.
This may bring back platform boots!
