Blunt was mostly scared to try her hand at dancing.
“There's a huge dance number, which was slightly intimidating for me,” Blunt admitted. “I think I did alright. I mean we did it 55 thousand times, so I hope they got something.”
Blunt shares daughters Hazel, 3, and Violet, 1, with her husband, John Krasinski. And while she thinks her eldest has a slight idea of what her playing Mary Poppins means, she hasn’t seen the original film.

“I mean, God knows what she thinks I do for a living,” Blunt quipped. “It must just be so confusing, you know? ‘Cause her version of movies is animated films, so she hasn't seen the original Mary Poppins yet. Yeah I'm sort of selfishly wanting her to wait for my version.”
