Doctor Who: Voyage of the Damned

Russell explains: "I like the whole Christmas-ness of a one off. It's my favourite slot of the year. When it was suggested to me that Kylie Minogue may like a part in it, you just nod over your glass of wine, and think "Yeah, yeah, not in a million years, but then they phoned literally the next day! I thought the most I'd get out of it was a meeting. I could tell people I'd met Kylie Minogue. I busked in front of her. I certainly didn't know that Astrid would die at that point. I told her that Astrid would probably do something that the Doctor disapproved of, like gunning someone down, so she'd want to be a companion but he'd refuse her. Every day I sat there going, "This isn't really going to happen, is it?" ...but it did!"
