Io9 also decided to have it's own analysis of the new Doctor Who series 5 trailer. It's a nice little pictorial analysis and has some interesting information and thoughts about what we can expect to look forward to when series 5 begins in the spring.
Go here to see the break-down of the trailer.
Note that Toby Whithouse's episode is the third one and is about Vampires in 16th century Venice. Hmmmm. Are these the same kind of vampires that are in his Being Human series I wonder? Oh, and the title is Vampires in Venice.
Also Mark Gatiss is writing the WWII episode with Churchill and the Daleks while Chris Chibnall is writing the Silurian two-parter.
I'm soooooo looking forward to more Doctor Who!!!
