Torchwood Children of Earth Trailer

Here is a trailer for BBC Sci-Fi drama Torchwood. There is a clip show at 0:19 of one of the main female characters Gwen talking directly to the camera as a video message, a cry for help. I like this style within the drama as it adds to the desperation on the character's and the human race. This is what I feel would be shown if Earth could send one last message to send it would be a call for help at total despair.
