Cara Delevingne has confessed she was “terrified” on her first day of shooting new movie The Face Of An Angel.

The 22-year-old British model and socialite has her first major big screen acting role in Michael Winterbottom’s film based on the Amanda Knox trial, co-starring Daniel Bruhl and Kate Beckinsale.

Cara revealed: “Being told I was working with them was just crazy, because they’re both incredible actors, I look at their work and respect it so much. So I was kind of terrified, so terrified the first day.

“But we all had a nice dinner and we all got on so well, I knew after that it was going to be so much fun.”

She added: “Daniel was such a dream, he was so sweet. I would get so nervous, [but] it’s like a family you know when you start doing these films, so everyone looks out for each other.”

Cara plays British student Melanie, who befriends director Thomas (Daniel) while he is in Sienna researching the murder case to make a movie.

The Burberry model – who had a small part in Anna Karenina in 2012 – revealed working with Michael was a very unusual style of filmmaking.

She explained: “The point of this film is that it is so real. Michael doesn’t want any acting, and that’s why he’ll leave the camera rolling, he wants you to improvise, because he wants a moment, even if it takes a long time, he’s looking for that certain thing and once he has it, he knows.”

Cara has travelled the world as a model, but revealed she loved the ancient Italian city if Sienna.

“It was incredible,” she gushed. “I’ve never been somewhere like that in my life, I loved it so much. And it’s funny talking to people who lived in Sienna, because they were like, ‘Oh it’s so boring!’, and all of us were like, ‘Are you mad, this is not boring, this is the most amazing place!’

“It’s so old and steeped in so much history, but you can look at it in different ways. When it’s light you can look into this amazing landscape and take it all in, that fresh air. Or you can look at it as dark, medieval, depressing, water dripping off things, very silent, eerie – it takes so many different forms. And I think that’s kind of reflective of how Daniel’s character goes through these dream states, these mad old Renaissance things.”

The Face Of An Angel is in cinemas now.
