“Kiernan was iconic in Mad Men, and I had even thought about her, I was like, ‘Oh I wonder if she’d ever do Betty,'” he said.
Kiernan as Betty?! Can you even???
Obviously, the part went to Lili Reinhart in the end, and can you imagine if it didn't??? #Sprousehart may never have become a thing!
Luckily for Kiernan, Roberto had the perfect role for her with Sabrina.
“When [Sabrina] moved from CW to Netflix, our casting director David Rapaport said, ‘By the way this is something Kiernan might be interested in,'” Roberto told EW. “There was no script at the time, but from the second he said that, for me it was sort of like, ‘Okay she’s Sabrina. I’m writing this for Kiernan.'”
