I got a recall to come in and read with Matt [the eleventh Doctor] and that was quite funny, actually, because, I wasn’t allowed to tell anyone that I was auditioning, what I was auditioning for, not even the people in the reception of the place that I was going to. So I had to give them a code name of ‘Panic Moon’. It was fun but it was actually an anagram for ‘companion’ which is quite clever.
