He also got the job with a little help from the Doctor himself.There's also plenty of detail about the kinds of films and television series he's worked on too especially locally.
Gordon explained: “I was doubling for David Tennant on Harry Potter, when he was stunned and thrown across a courtroom. Anyway we were chatting during the shoot and he told me he’d just been confirmed as the Doctor.
“A short while after that, I had a call from the production team asking me to go down as David had put my name in. It was a very nice thing to do, but he is a really nice bloke.
“Matt is a brilliant bloke too, in fact everyone is really great to work with. They’re like a big family and I love going back down to Cardiff.”
Gordon added: “The production of Doctor Who is a machine, but the attention to detail is staggering. I was dressed as the Doctor and had to fall down some stairs, and I wore the Doctor’s watch which was set to the right time. No-one was going to see it, but just in case, it was correct.”
