If you've been planning on seeing Star Wars Identities at the O2 stadium in London, England then you've only got a week left to go. The show finishes on the 3rd September to make way for a Prince exhibition. Prince as in the musician and not any member of any royal family. The show will then move to Utrecht, in The Netherlands so if you miss it and want to catch it elsewhere, you know where to go. All the major character models from the originals and the prequels are there such as Princess Leia and Darth Vader. There is no Jyn Erso and the sequels were limited to the androids (BB8, C-3PO and R2-D2). Its not just characters, there are vehicles such as the Star Destroyer on display too.
The worst thing about the identities is the positioning of the information boxes, right in front of the exhibition. It makes for taking photos very difficult, however, if you move to the side slightly then you can a nearly perfect shot.
In addition to information about Star Wars, there's also real world information which can be a bonus if you're trying to persuade someone to take you. :)
As you go round, there are information boxes that tell you how characters were designed. For example, Chewbacca might have looked more like a walking monkey than he does now with long pointed ears. Chewbacca's character was developed over a number of designs to what we like now.
Don't go expecting to seeing real-life face versions of characters because the emphasis is on the customes and vehicles. If you wanted life like looks of the characters then Madame Tussauds is your better bet which I talked about here albeit in minor detail. Before going you should check its still which it was at the time of writing.
