Star Wars is known for its avid fans, so what did the young fans in Leicester Square for Episode III Celebration Day have to say about it?

"I've seen the films lots of times, too many to count. I'm looking forward to seeing it a lot, but my dad says it was really hard to get tickets. We're going to see it on Thursday. My fave characters are Qui Gon Jonn, Darth Maul and Darth Vader."
"I like Yoda the most because he's a master Jedi. I want to be a Jedi when I grow up."
"I like Queen Amidala the most, and really like the outfits she wears. I've seen the others loads and am really looking forward to the new one when Anakin turns into Darth Vader. I don't think I'll be scared."
Chantelle and Callum
"I've seen them lots of times each. Obi Wan Kenobi is my favourite character, he's really good. He has loads of boss moves. We're going to see it on Thursday night."
"My favourite character is Darth Vader because he's the main part of the films. He goes from Anakin to Darth and he's in every one. I like that he is good, then bad, then good again."

"We've been here since 4.30am this morning. We've got our tickets for the film booked for Saturday. We'd love to meet the stars before the premiere. It's been great to see the Stormtroopers."
