Woo Who!!!! It’s a long time till November, when we should be seeing David Tennant in The Waters of Mars and even longer till Christmas, when we’ll see him finish his run as the Doctor in the big two part special. But there’s more!
David Tennant is to appear as the Time Lord in Doctor Who spin-off The Sarah Jane Adventures
And it won’t just be a quick walk-on, it’ll be a proper guest part, reuniting Sarah Jane with the Doctor for a special adventure. Russell T Davies says:
Viewers thought they may have to wait until November for the next full episode of Doctor Who, but this is an extra special treat. And it’s not just a cameo from David. This is a full-on appearance for the Doctor as he and Sarah Jane face their biggest threat ever.
I haven’t caught up with the second series of Sarah Jane yet, but I was quite impressed with the first one when I eventually got round to watching the DVDs. And a guest appearance from the man himself makes the next series something to look forward to indeed.
 Yes, I know I’ve used that before, but I don’t care!
