The BBC's official Torchwood website was recently updated after the transmission of last night's episode of Children of Earth and many new trailers are now available for viewing. An exclusive behind the scenes video with Gareth David-Lloyd was also uploaded onto the website last night and it has an approximate running time of three minutes and forty five seconds. It can be viewed here but please be aware that it contains spoilers for those who haven't yet seen the first or second episode of the series. This is the second of many Up Close videos for Children of Earth and the first video which went behind the scenes with Eve Myles can be viewed here but again, please be aware that it contains spoilers. The third video will be uploaded onto the BBC's official Torchwood website at 10pm tonight and that will go behind the scenes with John Barrowman. A second video going behind the scenes with John Barrowman will then be uploaded tomorrow and backstage videos with Kai Owen and Tom Price will be uploaded onto the website on Friday.
