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. A second exclusive behind the scenes video with John Barrowman was also uploaded onto the website last night and it has an approximate running time of two minutes and twenty seconds. It can be viewed here but please be aware that it contains spoilers for those who haven't yet seen the first four episodes of the series. This is the fourth of many Up Close videos for Children of Earth and the first three videos with Eve Myles, Gareth David-Lloyd and John Barrowman can be viewed here, here and here but again, please be aware that they contain spoilers. The fifth and sixth videos will be uploaded onto the BBC's official Torchwood website at 10pm tonight and they will go behind the scenes with Kai Owen and Tom Price. What do you think of this new video?
