Dick Van Dyke not sure about 'Mary Poppins' sequel

"Mary Poppins" star Dick Van Dyke says the upcoming sequel of the cult musical will be difficult.
Van Dyke, who played Bert in the Disney classic, is tipped for a return in the follow-up along with Julie Andrews, reported Daily Mirror.
"I'd have to see the script. Without Walt Disney, and the Sherman brothers to write the score, and Julie, it will be difficult, I think," Van Dyke said.
"Every day we came to work and we knew there was something magical going on. There was such a spirit. Walt was always there as a morale builder. We both said we were children looking for our inner adult - Walt was such a big kid.

"Sequels are traditionally not as good as the first. But I wish them well."
Emily Blunt will play Mary Poppins in the sequel with Hamilton's Lin-Manuel Miranda also to star.

Meryl Streep could reunite with her "Devil Wears Prada" co-star in the sequel too.
"Mary Poppins Returns" is set in Depression-era London and sees Mary return to the grown-up Banks children to help them once more, this time following a family tragedy.
The film is set for release on December 25, 2018.
