A slightly tweaked trailer for The Impossible Astronaut can now be seen on BBC1 and it contains a few new clips. The most interesting addition is the moment seen above which shows Amy witnessing a woman being zapped (and presumably killed) by a nasty electric blast.
Of course, there was a scene in the earlier UK trailer that also had a hand shooting lightning, so it appears this is another one of the abilities the Silence can pull off, along with mind wiping.
You can watch the new trailer below.
Thanks to John for the tip.
