Ashley revealed he finished filming his episode - Journey to the Centre of the Tardis - two weeks ago.
He’s little hestitant about giving away details of his cameo role, but he does reveal this: “in our episode it’ll be the first time people get to see so much of the Tardis.”
“You can’t beat being in Doctor Who - it’s something I’ve grown up with my whole life and working with Matt Smith was amazing. He’s a really, really good actor and just being a part of that huge BBC franchise was an incredible thing. And Jenna Louise Coleman is really good at what she does - it seems like she’s enjoying her job and I loved working with her.”
But it wasn’t too long ago that Ashley got in trouble with Doctor Who producers for tweeting a photo from his trailer that gave fans a sneak peak of his costume. “I nearly got sacked on my first day because they’re really strict about it. I was in my costume lying down on the sofa and I just tweeted a photo with the word ‘space’ - I didn’t say anything else. Five minutes later I had execs knocking on my door saying, ‘what are you doing?’ And then I realised there were signs everywhere saying ‘don’t tweet’.”
