Burn's casting was 'unoffically' announced a few weeks ago, though we had no idea of the character he was playing, or the significance of this role. Now it appears burn will be playing one of the four main leads, Owen Harper, Torchwood's resident medic. Burn was recently seen in both Bleak House and Layer Cake.

The scientist was seen there disecting a 'space-pig', and it's interesting to note that her scenes were Christopher Eccleston's first scenes as the Doctor recorded on screen! Already the woman's gone down in the Doctor Who history books.
With two men, and two women, it would seem that the Torchwood team is now complete. Well, except for that 'mysterious leader' Russell T Davies is so keen to tease us about. Anyway, filming is confirmed as "Starting next month" so that's the closest confirmation we've had of a May filming date for Torchwood.
More news as we get it folks...
