It’s that time again where those geeky americans, and we mean that in the nicest possible way, get dressed as Luke Spock Walker and Captain James Zulu Kirk and trundle of to Comic Con.

But now we realise why they do all this voyeurism  - this trailer.

We have been licking our lips over Tron Legacy ever since it was announced at Comic Con last year –  a new trailer has just been released and it looks amazing. Academy award winner Jeff bridges returns to the light cycle and with Daft Punk doing the sound track, it could well be the film of 2010.
