A lot of the time with child actors, you get the feeling they're trying to have a kind of poise or presentation that's beyond their years that might be put on, but also might be because they've spent years just hanging out with adults and they don't even have a sense of what it's like to grow up with kids their own age.

Some people manage to make that transition from child actor to adult actor seamlessly. But I felt that if I spent my whole life on a film set without taking a few years to do something else, all I would ever know about was film sets.

Having been a child actor, I remember how directors would trick me to get good performances out of me. I don't think you need to do that.

'At Freddie's' takes place in 1960s London at the Temple Stage School for child actors. It has a plot that makes you feel sorry for the people who have to write summaries on the backs of books.

We focus a lot on culture specifically at Twitter because of this spotlight, and of the fact that we don't want to end up like the child actor who found success early and grew up all weird and freaky.

Going from a child actor to an adult actor is not an easy thing, and I was sort of lost in a no man's land for a while, trying to figure out who I was as a person, and going from a young actor to an adult actor.

I think every child actor has that moment where they're like, 'OK, I'm not the same person that I was, and you guys need to see me as something different.'
