Jenna-Louise was nominated at the 2006 National TV Awards for Most Popular Newcomer category.
Jenna-Lousie: (on her Dr. Who character and her relationship with The Doctor) I like that she holds her own. You know, The Doctor's this amazing man, and she's like, "You know, cool. I think you're amazing, but so am I." So, it's a nice double act.
Jenna-Louise: (on what she knew about Dr. Who before she got the role of Clara) It was my gran's favourite programme but I just never really watched it. I didn't know anything about the role of companion, really. I'd never actually seen a Cyberman.
Jenna-Louise: (on being recognized in public) I think I am just too short, I don't get recognised. We have had this discussion, Matt is taller than me and has quite a distinctive walk.
Jenna-Louise: (on her character in Waterloo Road) She becomes the ringleader and it's almost as if she enjoys it. I think it's like a a defence mechanism for her, it makes her feel better when she sees others unhappy.
Jenna-Louise: (on working with Matt Smith) He likes to tease me. He started off gentle. He was really, really polite and gentlemanly. Of course he still is, but now it's kind of like an older brother kind of thing. You can see he was kind of sussing me out really to find out which points he could tease me. He's quite a big wind-up.
Jenna-Louise: (on her Dr. Who character Clara) Clara is also quite collared actually and she's quite chic. I kind of liked the idea of that. She looks a little bit cutesy, but she's got biker boots on. She's the kind of girl who sits in a library reading, but she's actually quite a go-getter, action fighter with these little biker boots. She'll take you by surprise. She's not all that she seems.
Jenna-Louise: (about the Dr. Who set) It's impossible to keep still while you're in there as there is so much to look at and play with. It was a fun time for us to have our own little home to inhabit.
Jenna-Louise: I had my first scenes with the TARDIS the other day. In fact, I had an argument with the TARDIS. I fell through it. I had to bang on the doors, and the doors weren't shut properly, so in front of all the crew I went flying through it. It's on camera. I thought, 'Oh my goodness, I've broken the TARDIS, everyone's going to hate me.'
Jenna-Louise: (on hearing she'd got the part on Doctor Who) I was in Marks and Spencer holding an avocado having the debate of what goes best in a salmon salad when I got the call from my agent, and it was kind of bewildered excitement, confusion, 'Really? Oh goodness', all sorts of emotions. After I hung up, I though, 'I really can't carry on shopping', so I just put the basket down and left Marks and Spencer, and just went for a little walk and tried to digest.
