British model Cara Delevingne is to make her acting debut in Sky Arts' upcoming drama Timeless and co-star, long-time Britsh actress Sylvia Syms, has compared her to icon Audrey Hepburn.

Syms, 80, said "I worked years ago with a beautiful girl who became very famous," in an interview with the Evening Standard. "This child [Delevingne] here has the same quality which is known as not acting for the camera."

"She is real and an absolute joy to work with," continued Syms. "I was told I was going to work with a model and I had never heard of her but I literally fell in love with her on the first day. The other girl I loved was Audrey Hepburn."
