One to watch: Antonia Clarke, actress, 18 When I was aged 15 I didn't get into the school play, so I decided to get myself an agent and prove myself. Her mission is complete with a role in her first feature film Les Misérables, out later this month, playing a prostitute. The West Londoner has just left Downe House School, in Berkshire, where she juggled her A-levels and filming the recent ITV series A Mother's Son. She next appears in ghost drama Lightfields in February.
