And it comes with this:
She looks familiar. I've seen her somewhere before, right?
You've dropped yourself in it there. The answer is yes if you are a fan of a certain strain of American TV. Holland played Mischa Barton's naughty little sister in two seasons of The OC, and was a spacey model in a few episodes of Gossip Girl. She was discovered by Steven Spielberg - in his garden no less.
What, she was a stalker?
No, she was seven years old at the time, playing with his kids. Her stepdad is Brian de Palma.
Connections like that won't have done her any harm. But is she actually any use in Genova?
Yes she is. There is a lovely naturalness to her performance. Like Henry James's Daisy Miller, Kelly is an American girl in Europe, eyes opening to a new way of seeing the world and testing her place in it. Winterbottom's camera seems at times to drift around her, entire scenes with her barely saying a word.
Which sounds a million miles from the OC's articulacy overdrive.
Right you are. That said, Kelly does what every self-respecting, boy-mad 16-year-old would do in a new city: ditches her little sister and goes off in search of a bit of local action.
What next for Holland?
Well, she is already one step ahead of her screen sister, Mischa Barton, whose handbag choices have made a bigger splash than her film roles since The OC. Expect Holland to distance herself from the TV stuff. She's already on to her next film, a hellfire apocalypse drama called Legion, with Paul Bettany as the archangel Michael."
