“It was so much fun getting to act with the different Doctors (Matt Smith and David Tennant) but it was quite scary and intimidating at first.”On John Hurt, who plays the other Doctor in the special, she said:
“He is so much fun. He’s got the most amazing stories, he’s just fantastic. And you see him on set and he’s got that amazing voice and he doesn’t do anything – he just starts saying the lines and you’re like, ‘Oh my god, you are the best actor I’ve ever seen.’”The 50th anniversary special airs on 23rd November on BBC One.
