The latest film in the epic Narnia saga, Prince Caspian, opened in America this weekend.
In real life it's three years since the first film, but when Peter, Susan, Edmund and Lucy revisit Narnia, it's 1,300 years later.
The stars have been giving their views on the CS Lewis adaptation.
William Moseley, who plays Peter, said this film is darker than the first: "Peter has to evolve into a greater leader than even in the first film."
In this film the family don't go through the wardrobe to the magic kingdom. Instead it's via a London Underground station!
The children have to help rebuild Narnia, with the aid of Trumpkin the dwarf, a talking badger named Trufflehunter and a number of talking mice, centaurs and fauns!

Skandar Keynes, who plays Edmund, said the film was a battle of good and evil.
He added: "I think you can go in and take that message if you want or you can just enjoy yourself for two hours and it's great fun."
Georgie Henley, who plays Lucy, was just eight when she started filming. She said being in the films has helped her mature.
She said: "Also I feel like I've become a stronger person which I think is good."
The film opens in the UK on 26 June.
