How the magical 'Mary Poppins Returns' bathtub scene was really created will blow your mind. 

If you’ve seen Mary Poppins Returns, you’ll know just how truly magical the new film is.

From the catchy songs to the lovable dance routines, there was something in it for every Disney diehard fan.

But besides being incredibly magical viewing, it seems the film itself truly made the impossible possible.

A new behind-the-scenes clip released by Disney has showcased the impressive lengths director Rob Marshall went to to make the magic of Mary Poppins come to life.

Do you remember the bath tub scene?

After singing along to ‘Can You Imagine That’, Mary Poppins and the Banks children completely disappear into a bubble bath, reappearing in a magical underwater world.

But this wasn’t the work of clever editing or CGI.

Nope, this was actually real.

As the behind-the-scenes clip revealed, the set design department actually cut a hole in the bottom of the bath tub and connected it to a slide for the actors to glide down as they fell into the tub.

In the video, viewers see actress Emily Blunt slide down the steep slide until she appears under the stage, covered in bubbles.

Um, amazing.

In a Q&A about the film, Blunt explained why a real slide was used for the scene rather than CGI.

“Rob, and everyone involved, was very insistent that as much as possible we built practical sets that we could very much interact with and be a part of,” the 35-year-old explained.

“So what they did with this bath, which the kids thought was the best thing ever, was that they actually carved a hole in the bottom of the bath and had a slide that went under the stage. But it was a drop! It was fast and steep. Then they filled it up with bubbles so you just went down the slide.”

Although Blunt wasn’t a big fan of the slide, she said the kids in the movie had a whole lot of fun.

“They actually carved a hole in the bottom of the bath and had a slide that went under the stage. But it was a drop. It was fast and steep. So the kids did theirs 20 times; I think I did it twice.” #EmilyBlunt talking about THAT shot.

“They must’ve done it 20 times, the kids were like, ‘Can we do it again?’ They loved it,” she said.

“I was quite scared. My stunt girl did it before me and said as long as you [fold enough] you won’t concuss yourself. So the kids did theirs 20 times, I think I did it twice and then said, ‘Have you got it? Is that it?'”

Honestly, we really wish we could have a go on that slide…

Mary Poppins Returns is currently showing in cinemas across Australia.
