As a young child, Wunmi Mosaku always had her sights set on a career in acting, inspired by her love of the 1980s musical Annie.

"I watched Annie every single day after school," said 39-year-old Mosaku during a recent interview on The Graham Norton Show.

"I said to my mum and sister 'I don't want to do maths and economics, I think I want to act'.

"They were like 'how do you do that' and I was like 'I don't know'."

To answer her mother's question, Mosaku decided to google the cast of her favourite film in search of some much-needed insight into how to break it into the acting industry.
