Emily Blunt still 'figuring out' her approach to iconic Mary Poppins role

British actress Emily Blunt is still deciding how she will tackle the role made famous by Julie Andrews in the Mary Poppins sequel.

The Girl On The Train star, 33, has been cast to play the beloved nanny from Disney's 1964 children's film in the sequel Mary Poppins Returns. The movie is a co-production between Walt Disney Studio's, and Matt Platt Productions, and will also star Meryl Streep and Hamilton creator Lin-Manuel Miranda

In an interview, The Devil Wears Prada actress admits she is yet to work out how she will follow Julie Andrews in the role ahead of rehearsals which will begin in November (16).

"I think I just have to do my version of it," she tells HeyYouGuys.com. "It's quite hard to sum up what my version of it is yet. I think I'm still trying to figure it out and work it out and I'm sure I'll have a better idea by the time I start shooting."

Julie Andrews' version of the magical nanny has become one of cinema's most beloved characters, but Emily says she will look to draw upon P.L. Travers' original series of novels rather than Julie's performance.

"I've been much closer to the books," she explains. "I think the books are offering a lot of different ideas."

The film will follow Mary revisiting Jane and Michael, the two children whose care she was charged with in the original movie as adults, with her now having to bring joy and new experiences to Michael's three children.

Mary Poppins Returns is scheduled for release in 2018.
