Another version of the Doctor Who Series 6 trailer is airing on BBC1. It isthe same as the one that came out yesterday, but there is one difference. In the old one, there is a scene where the TARDIS console explodes. While the alternate version sees that scene replaced with a clip of a monster earlier described as a grey. Check out the vidio below.
