Bradford schoolgirl Georgie Henley is all set to go back through the wardrobe to the magical land of Narnia and 10,000 fans will be able to join her in what is being billed as the biggest UK movie premiere in history.

Georgie, who attends Bradford Grammar School, has reprised her role as Lucy Pevensie, the youngest of the four siblings who journeyed to another world in the hit film The Lion, The Witch and the Wardrobe in 2005.

On June 26 the second book to be adapted from CS Lewis's Narnia series, Prince Caspian, goes on general release, featuring 12-year-old former Ilkley Upstagers drama school student Georgie once again in a starring role.

But a week before that Georgie will join fellow young actors Anna Popplewell, William Moseley and Skandar Keynes, who play her on-screen siblings Susan, Peter and Edmund, as well as newcomer Ben Barnes (the Prince Caspian of the movie) and Liam Neeson, who voices wise lion Aslan, on the red carpet for a sparkling premier.

Tickets go on sale today for the event, which will take place on Thursday, June 19 in the 02 Arena in London, and is being billed as "the biggest single screen, shared audience experience ever".

The film's producers, Disney and Walden Media, will be donating a portion of the profits to the Great Ormond Street children's hospital in London.

Georgie, a former pupil of Moorfield School in Ilkley, has already been making a name for herself both on and off the set of the movie.

Star Ben Barnes, 26, revealed that Georgie incessantly teased him during filming about his burgeoning heart-throb status and the moody poses he adopted for the promotional movie posters. He said: "Georgie comes up to me and says, Ben, do this!'," asking him to replicate his poster shot.

At the recent New York premier of the movie, Georgie joked with reporters on the red carpet approach to the event by saying she planned to "drink the night away" and "have some fun".

Prince Caspian, made by New Zealand-born director Andrew Adamson with a reported US$100 million (£50 million) budget, picks up where the first film left off. In The Lion, The Witch and the Wardrobe, the Pevensie children discovered the secret way to the world of Narnia, where it was permanently winter under the spell of the evil White Witch (played by Tilda Swinton). With the help of Aslan the lion, the Pevensie children defeated the White Witch and returned to wartime Britain.

In Prince Caspian (actually the fourth book in the cycle as Lewis, who died in 1963, intended them to be read) the Pevensies return to Narnia. But although just a year has passed in our world, Narnia has moved on more than 1,300 years. An evil human empire has banished the magical talking animals that once populated the world, and it is up to Lucy and Co to help the rightful heir to the throne, Prince Caspian, set matters straight.

The third Narnia movie, Voyage of the Dawn-Treader, is due to be released by Disney/Walden in 2010.
