Doctor Who's new companion, actress Karen Gillan, says she's "completely nervous" about the airing of her first episode.
The 22-year-old admitted the series debut was always going to be daunting but that the production team were all "really proud" of their work.
Doctor number eleven - Matt Smith - will also be introduced when the show returns at Easter.
Gillan said her on-screen partner would win over fans and silence those who've raised eyebrows about choosing a relatively unknown young actor.
"What Matt's done is something completely incredible", she said. "He's completely made the part his own and I think people really are going to fall in love with his Doctor."
