By the end, it's changed her for the better and she becomes unafraid of being a child.
HBO has released its first teaser trailer for its upcoming series, Westworld.
Each of the characters in 'The Lion, The Witch and The Wardrobe' has their own journey and Susan's no different.
Like Peter, she feels the obligation of looking after her younger brother and sister and it's something that has made her grow up too fast - being saddled with all that responsibility.
Today Anna Popplewell and William Moseley, explain why Susan’s and Peter’s last journey into Narnia shouldn’t be missed…I suppose I should be used to it by now, but the scale has upped itself pretty-much proportionately going into this film. Having another fantasy race of people in the Telmarines, meant that we had hundreds and hundreds of extras playing soldiers on set.
That meant bigger cameras and bigger depart-ments and it just meant that everything was upped in terms of the scale.
In the first movie, Susan took on a very motherly role because the children had been evacuated – she feels very responsible for her siblings.
The 26-year-old English actor Ben Barnes, a definite star in the making, takes on the title role and he is joined by Peter Dinklage (The Station Agent) as the Red Dwarf Trumpkin, Warwick Davis (Willow) as the Black Dwarf Nikabrik, and Sergio Castellitto - a huge star in his native Italy - as King Miraz.
In terms of voiceover, Liam Neeson will resume his role as Aslan and Eddie Izzard steps in as Reepicheep the mouse.
