Theyve got something really good under wraps until Christmas.

We just focused on this story and these people and this moment.

Miranda remembers that night just a bit differently: That was areallystressful show, he laughs.

I felt like I was auditioningforMary Poppins, the person.

Miranda callsPoppinshis first big movie, but acknowledges how unusual the film actually is from the typical big-movie experience.

Where does that part come from?

And you realize, it comes from Were never coming back to Buckingham Palace to get a second take.

The adrenaline source is in getting it right in that moment.

Just say I wasnt involved at all.

What would I want to see in this film?

I knew I wanted to see an animation sequence in the hand-drawn 2D style.

But the most important thing was an emotional story.

How do you move through that?

Theyve also lost a sense of wonder and joy, says Marshall.

We live in such a fragile time that we need this film.

I certainly felt that I needed it.

If Marshalls wish comes true,Mary Poppins Returnsmight deliver some similar optimism to audiences this Christmas.

I just cantwaitfor people to see it, gushes the actress.

I feel like we have this little secret all tied up in a bow.

Why cant we just give it to them today?

As Mary Poppins would say: patience, Meryl Streep, patience.
