Emma Watson (Hermione Granger in Harry Potter) about the show
New stage musical Chitty Chitty Bang Bang has got the thumbs up from Harry Potter star Emma Watson.
Emma, who plays Hermione, was among the celebrity audience at the world premiere at the London Palladium.
And she spoke exclusively to Newsround Online after the show.
"It was absolutely fabulous," she said. "There was lots of magic. It was very cool."
Emma really liked the costumes and the details in the set design - and all the glitter that falls from the ceiling during the show.
Among the celebs were James Bond actor Pierce Brosnan and Oscar winner Halle Berry.
The first night audience loved it too, and gave the show a huge standing ovation.
Evil Child Catcher
Chitty Chitty Bang Bang tells the story of a magical car made by an inventor called Caractacus Potts. It also features an evil character called the Child Catcher!
"There was a great atmosphere, everyone clapped along to the songs," said Emma.
She said she'd like to be in musicals as she loves singing and dancing.
But Emma admitted she was baffled by the special effects in Chitty Chitty Bang! Bang.
"I've absolutely no idea how they managed to fly the car on stage!" she said.
Talking of flying cars, Emma's currently filming Harry Potter and the Chamber of Secrets.
But you'll have to wait till November before you can see Harry and Ron take to the air in the Weasley's old Ford Anglia
