Julie Andrews has full confidence in Emily Blunt's ability to do justice to the role of Mary Poppins.
While Dick Van Dyke announced he will be returning for the sequel, Andrews tells ET's Leanne Aguilera that she doesn't think she'll be a part of it, but she is thrilled to be able to pass the torch to the Golden Globe-winning actress.

"Emily Blunt is going to play Mary Poppins and I am a great fan," Andrews says. "I think she is terrific and a perfect pick."
Disney's upcoming sequel to the classic 1964 film is set in Depression-era London, where a grown-up Jane and Michael Banks are visited by Mary Poppins after their family suffers a personal loss. Poppins uses her magical skills to help Jane, Michael and Michael's three children rediscover the joy missing in their lives.
Instead of reprising his role as Bert the chimney sweep, Van Dyke will portray the son of a greedy banker. Other characters include Lin-Manuel Miranda as a lamplighter, Angela Lansbury as the Balloon Lady and Meryl Streep as Poppins' cousin.

"It is not a remake of the old Mary Poppins," Andrews explains. "It is making all the rest of the stories that Walt Disney had stored in his vaults and now they have made a completely new Mary Poppins story."
Andrews is working on some new stories of her own on the Netflix children's series, Julie's Greenroom.
The Oscar winner executive produces the program along with her daughter, Emma Walton Hamilton, and she's got some special guest stars along the way.
