Emma Thompson is the antagonist and we rarely see her in a villainous role absolutely but she is able to play the bad guy for once.
“I drew on the life, obviously. I think if my husband were in the room, he’d say, no acting required, really. I had such fun doing her because I think I’ve been asking for quite a number of years if I could be a villain, a proper villain. I spent decades playing what my mother used to call, “Good women in frocks.” And, now I got to play a really evil woman in frocks. But, oh boy the frocks. I mean they wore me, actually, I had just the best, best time. Every time Em and I would come on set, we’d just look at each other and walk around each other like we were sculptures or works of art or something, which we were”.
