Those scenes were hard to write, and we all felt our lead characters pain.
We wanted to feel her joy as well reflected even in her final moments.
How did you go about planning out the final season?
But also, her marriage to Darnley was a bold move thatcouldhave worked.
It could have brought her power in England.
How could we not tell it?
How you would pace it out?
Were there parts of Marys story you really wanted to tell but didnt get the chance to?Yes.
Which led to a secret that drove Mary and Francis apart, for example.
Reignis also known for its amazing costumes.
How closely did you work with your costume designer?
then yes, we collaborated.
Okay, Im exaggerating, but as the show went on, only slightly.
Battles we would need to build dozens of costumes for, pregnancies, and especially weddings.
Oh, those wedding dresses amazing.
Were you there during filming?
Lets not talk about it, or Ill get sad.
I was so happy to see Catherine choose herself over her children in the end.
It also worked as a series finale, as a culmination of an arc for her.
