Been thinking about this one, both in terms of my own life, and also in terms of media, specifically thinking about Star Wars. Don’t ask,
Genevieve O’Reilly had films a few scenes for Revenge of the Sith that ended up on the cutting room floor. Ten years later, Star Wars: Rebels brought her back as the voice of Mon Mothma. Two years on, she appeared in the flesh in Rogue One. And now, after 20 years, because of Andor, she’s an icon within Star Wars. I can’t think of another actor who’s had that kind of arc.
