Sunetra Sarker, Dr Zoe Hanna in Casualty, likes the 'family atmosphere' created on the set in Bristol. The BBC's longest running television drama was filmed locally from 1986- 2011.

Matt Thompson worked as an extra and was surprised by the length of a working day. 'You could tell the experienced extras, they'd brought books and laptops.'

'It's very busy like a real hospital. We're always welcoming new characters so it never seems like the same day.'
