The star of the new big budget Cinderella movie has been talking to Newsround about what's it's like to play a fairytale princess.

Lily James plays the lead role in Disney's latest version of the story and says it was a dream come true.

Cinderella first hit the big screen in the 1950s, as an animation, and now it's back in the cinema with real-life stars and costumes - and a seven-minute (sort of) sequel to Frozen too.

In total, 1.7 million crystals were used to make the costumes and recreate the magical fairy tale world.

But what exactly goes into creating a wardrobe worthy of a blockbuster?

Jenny went behind the scenes of the Cinderella premiere to find out.
