Don't forget that a brand new trailer for Series 3 of Torchwood, Children of Earth, will be available to watch on the programme's official website from 9pm tonight!
The 60-second preview has been put together for the ComicCon 2009 and will be simultaneously broadcast at the event, which is taking place today in New York.
Children of Earth, which will air on BBC One later this year, has been described by producers as being 'one epic story told over five nights'.
The mini-series re-joins Captain Jack (John Barrowman), Gwen Cooper (Eve Myles) and Ianto Jones (Gareth David Lloyd), who are still coming to terms with the death of two of their closest friends, Owen Harper and Toshiko Sato. Despite their pain, they have a job to do.
And this time they are faced with their fiercest threat to date - one which throws the future of Torchwood and the entire human race spiralling into danger. They battle against the odds but do they stand a chance of saving mankind?
