What gives?I bought my computer in, like, 1962.
So, if I ever have to do anything official, I use my husband’s computer.
He always has up-to-date equipment!
What was the most recent episode ofSnowpiercerlike to shoot?It was pretty full-on.
I don’t think I sat down for the whole time.
But I really really enjoyed it.
Because we see her making the decision to leave her daughter behind and to start the train.
That must have been an emotional scene to shoot.It was such an intimate set.
The whole episode felt so internal in a way.
How close did you get to the rats?Oh,reallyclose.
I was like, is she wearing gloves is she not wearing gloves?
I was so grateful that we had decided that she was wearing gloves.
So, you actually picked the rat up?I picked the rat up.
I was like, “Maybeyoucould practice first before I do it, would you mind?”
I’m so glad we did, because he did it and the rat bit him on the hand.
But I had a lovely time with the rat and its various siblings that also worked on the show.
In the episode, you did get to verbally joust with Sean Bean.
That looked like fun.I feel like it’s such a fun character for him.
He'’s clearly really cruel but his cruelty comes in this really charming bon vivant package.
He presents very different from the way he actually is.
You’re starring inSnowpiercerand your husband is inWandaVision.
It must be high times at the Connelly-Bettany household.Yeah.
It’s really fun.
We both have shows that have come out at the same time.
I thinkWandaVision’s great.
I think it’s fantastic.
I’ve seen it.
I’ve seen all the season.
So, Iknowwhat’s happening.
Watch a teaser for next week’s episode ofSnowpiercer, above.
