Last week, the first images of David Tennant's Doctor Who turning up in The Sarah Jane Adventures were released. In case you've not seen them before, we've attached them to this story. They should be beaming at you right now.

Today, the BBC has also revealed a brand new promotional shot showing David Tennant and Elisabeth Sladen ready to take on the ills of the world. This is in advance of the start of The Sarah Jane Adventures' third series, which is set to start on Thursday 15th October with a two-part battle against the Judoon.
