This one looks better every time I see a new trailer. You can see them all at the Planet 51 official website, so you will know if you want to see it come November. And then there is the trailer for Tokyo!, the movie William Gibson tweeted about today (or yesterday, depending on your time zone), also looking very interesting. Robert J Sawyer, who already holds a number of awards, including the Hugo and Nebula, is up for another one. The Aurora Awards has his short story collection Identity Theft and other stories on the short list for Best Long-Form Work In English. Until the voting ends, you can read it online here.
