My mum and dad have always enjoyed life, and it's something that's been instilled in me. I wake up in a good mood most mornings.
By the age of 18, I was very fat. My dad would say there's a Spall fat gene. But I was fat because I ate loads. I used to go and buy six or seven chocolate bars and eat my way through them.
I never mind talking about my dad. I'm proud of who he is, and being his son is one of the things I'm most proud of. To be constantly compared to someone so brilliant, who happens to be your dad, is cool.
One of the biggest gifts you can give a child is confidence, because confidence will take you miles - more than talent, more than anything else. So yes, I want my children to have confidence and to be kind.
Doing 'Prometheus' was what you imagine being an actor is like when you're five. In a spacesuit, on another planet, getting killed by an alien. It was a real treat; it felt like being a part of movie history.
There's nothing so unattractive as vanity... particularly male vanity.
As an actor, you try and be cool, but one of the reasons you become an actor is because you're a film fan. And then you're like, 'Oh my God, Ridley Scott just spoke to me!'
I've done loads of things people have never seen - dramas on BBC4 and plays upstairs at the Royal Court and the Bush - and because I didn't go to drama school, they gave me an education.
Being kind is the most important thing I've ever been taught. That's what my parents always told me - more important than ambition or success is being kind to people. The cornerstone of my life. What I aspire to is to be kind.
For a man, there's a big responsibility that comes with having a boy because men are made by their fathers. If you've got a good productive man around it's better. I have such a close relationship with my dad and that responsibility to produce a good man is something I think about.
It's properly scary playing a leading man. Growing up, I always wanted to be a character actor.
