Preview for Sarah Jane Adventures Series 4!

If you're a fan of the Doctor Who spin-off, you'll like this - previews and teasers for the upcoming fourth series of The Sarah Jane Adventures are starting to trickle through.

In the picture above, you can see Sarah and the gang posing for a photo (say cheese!), oblivious to the bevy of monsters creeping up behind them. And in the video below, you'll get a glimpse of some scenes from the new series. Including an appearance by Matt Smith as The Doctor! The last time Sarah Jane saw him, he looked more like David Tennant and was sloping off to regenerate...

I don't know what those colourful robots are, but they're powered by some pretty swish CGI!
