Emily Blunt recent spoke to Entertainment Weekly about taking on the legendary nanny character. She had this to say. about her inability to spin while dancing, and how many takes had to be cobbled together for just one scene.

"I have an inability to spin when I'm dancing. It became this in-joke with Rob and John. They were like, "Do not make her turn." Truly, I don't know why I can't. I can pick up other steps fine. And I think the one spin that they actually ended up using in the film... Rob had to use three different cuts to execute. Not three spins, but three-quarters of one spin that I could barely make around. [Laughs] So I don't know if I ever honed that skill. But certainly with three cuts in there, it looked like I did."

She went onto say this about discovering the magic behind the character.

"The mystique of her is kind of what I love. And this strange duality, that you've got this rather stern front and yet the lining of her coat is completely batty and eccentric and that's just who she is. It's like, when she goes on these adventures, she needs it and wants it just as much as the kids. She loves going on these adventures. It's like her fix, you know? And yet, she pretends it doesn't happen, and she makes it all about you. So because she is mystical and because you don't really know what she is and she's so open to interpretation of what you feel she is or who she is to you, I didn't mind the unknown of it. It's something for me think about and imagine my version of what I think she is and where she goes or who she looks after."
