Naomie Harris knew she wanted to be an actress by the time she was three.

The 'Spectre' star - who was appearing on TV shows before she'd reached her teenage years - has credited her strong work ethic and determination as the keys to her career success.

The 39-year-old beauty shared: ''My work ethic was really strong and it got even stronger as a result of being a child actor. You are in a very adult environment and are expected to behave like an adult.

''Nobody allows you to get away with stuff that you normally get away with as a kid, so you kind of grow up a bit too quickly.''

However, Naomie admitted her early success and nerd-like approach to school life made her a target for her classmates.

She told the Sunday Times newspaper: ''I was bullied at school. No one wants to be your friend, no one picks you for the games. There was a lot of jealousy because I was on TV.

''At the time it was pretty miserable, but I always had this goal and this vision of what I was going to achieve, so I held very strongly to that - and, actually, being bullied fuelled that dream.

''In some ways I have to thank those bullies, because I don't think I'd be where I am today without that experience.''
