Opinionated director Sofia Coppola

Sofia Coppola admits she is an opinionated director but never ''yells'' at her cast and crew.

Sofia Coppola is an opinionated director.

The 'Lost in Translation' director - whose father is legendary filmmaker Francis Ford Coppola - said although she doesn't believe in shouting at her actors, she is quite outspoken when she wants to be.

She explained: "I'm quite opinionated. I think you have to be as a director.

"I'm not a yeller though. I think I'm strong without having to be loud. I'm clear about what I'm setting out to do. And I'm persistent. You need that too as a director."

Stephen Dorff - who plays a bad boy actor who is forced to sober up when he receives a visit from his 11-year-old daughter in Sofia's new movie 'Somewhere' - agreed with her and added she is a director who has "balls".

He told British Vogue: "I love how she is so elegant but she has balls. She is sweet and casual and she never raises her voice but she knows exactly what she wants."
