For those who have been watching season 4 of Doctor Who I have at treat. The BBC released a B trailer that is only available in the UK. I managed to intercept a subspace mail packet and get a copy of it. Savor it because 12 Andorians, a Deltan, and 4 Vulcans died to bring it to you. If you're looking to stay unspoiled for this season I recommend you not click on the link.
