I can hear the call box sounds as I write this post. The Doctor is arriving for series four starting on BBC one April 5th. BBC has posted the trailer on their website.

Unfortunately they are still not making it embedable but I have hope that soon they will become more web friendly in the mean time I wait.

The trailer is exciting we get to see some more footage of the Ood, and the Sontaran. I was also excited to see a short clip of Rose!

There is also an older trailer for series four in which we get to hear an Ood speaking. The trailer is under Voyage of the Damned section at the bottom titled "A taste of Series Four".
