Juror profile: Marcia Thomas Twenty years old, a very independent, strong-willed single mother. Highly opinionated and quick-tempered, Thomas finds it difficult at times to accept help from others -- especially her mother with whom she has a strained relationship and a difficult history. One of the more diplomatic jurors. Young actress Nina Sosanya has appeared on Masterpiece Theatre as Joanne Fagunwa in Prime Suspect 2. She found one scene in The Jury a particular challenge: 'It was quite emotional and difficult to film. When researching our roles as jurors we were given a number of videos which contained a variety of case studies on people who'd done jury service. They were quite insightful in the way they showed the impact the different cases had on jurors. In some cases the trials had happened years ago and yet people were still suffering emotionally.'
