I think I'm turning British-ese. On the heels of our report that BBC America is bringing new batches of Doctor Who and Torchwood to U.S. shores this summer, we now have news as to who will be playing the new Doctor Who's companion in Season 5.

Relative unknown Karen Gillan has been tapped to accompany incoming Doctor Matt Smith on the TARDIS' next series of adventures, premiering on the BBC in 2010.

"I am absolutely over the moon," the pretty Scot tells BBC News of her good fortune. "I just can't wait to get started."

Gillan is not a complete stranger to the Whoniverse, having played a soothsayer in the Season 4 episode "The Fires of Pompeii."

She also may be familiar from her run on the U.K. sketch series The Kevin Bishop Show.

Incoming show runner Steven Moffat says that although they auditioned a bevy of "amazing actresses," as soon as Gillan walked through into the room, "the game was up. [She's] funny, and clever, and gorgeous, and sexy."

The choice of Gillan to accompany Smith is fitting, as Smith is also a relatively fresh face to audiences. In fact, Smith is the youngest actor to ever play Doctor. He succeeds David Tennant, who last Lords over time in the five specials arriving on BBCA starting this summer.
