Billie's Back!

"She's changed. She's hardened. She's been through a lot in her parallel world," explained Billie in an interview for the latest issue of Doctor Who Magazine.

"I think she's been through emotional turmoil. She's quite sad and lonely, but also really bolshy and - that great quality that Rose has - just so headstrong and single-minded."

When asked about the difference between technically demanding scenes and emotional ones, Billie commented:

"It's just a different kind of intensity, but equally as intense, because you really have to focus. You're imagining things, seeing things, that aren't there. That takes a lot of concentration. But this series will make you cry. That's a promise."

Other things to look out for in the new issue include: actors Steve Pemberton and Joe Dempsie talking about their respective roles in Silence in the Library and The Doctor's Daughter; executive producer Russell T Davies explaining what happened on a recent trip to the BAFTA awards; and previews of Midnight and Turn Left.

Doctor Who Magazine is out 29 May, price £3.99.
