How do you feel about the Broadchurch effect?
We all loved it when we were filming and the scripts were brilliant so you hope people aregoing to get that, but as the audience built it was incredibly flattering that people loved it as much as we did. It is great if people enjoy what you do. I was gripped as well because I hadn't seen everybody else's scenes and it was the way that everybody on the cast and crew really kept the secret - it made it special. We had each other if we needed to talk about it, but I did get a lot of texts and emails from close friends and family asking me who did it and I quite enjoyed the power of saying no to them all!
What was it like winning a BAFTA for your role as Ellie Miller?
That was incredibly special. Just amazing and makes me eternally grateful to Broadchurch and Chris Chibnall for giving me the chance to play that role. To win one anyway is pretty special, but to win one for something you feel really affectionate towards is really lovely.
How have the new cast fitted in?
Marianne (Jean-Baptiste) is the coolest women on the planet. Everyone loved her. Charlotte Rampling is amazing. I was nervous about meeting her as she is a proper legend but she is so sweet and brought everybody a box of chocolates on her last day. Eve Myles is so funny, she has told me some of the worst jokes I have ever heard yet still I think about them in the middle of the night and laugh. And Phoebe (Waller-Bridge) is a very good friend of old so whenever we were at unit base at same time it was lovely. She is an extraordinary creature;
the funniest human I've ever met. Broadchurch is the best job; an absolute treat. It was a long job but there wasn't one day when I wasn't excited about getting up and going to work. I feel very lucky.
What was it like being back in West Bay?
Like going back to a childhood holiday, you know when you go to the same place each year.
"Yay we're here again and the doughnut shop is open". And the people are incredibly nice considering we must turn it upside down for them but they welcomed us back.
