Here is an extended trailer for Torchwood: Miracle Day that airs on Starz and the BBC this coming July.
This one minute and 46 second trailer comes from the Starz official YouTube channel. There is a lot of Eve (as Gwen Cooper) in this one and she looks really badass! July can’t come soon enough!
If you live outside the US you can watch it here if the video is blocked.
Update: Starz had the old trailer removed, but here is a new one from their official YouTube channel that runs 1:46 and includes some additional scenes.
