I was doing things that weren't good for me. So I checked into the Churchill Priory clinic. It was the best thing I've done for ages.

Every season, I'm like, 'Who knows if I'm going to get another job?'

Now I can walk into a room full of people I don't know and do my job. That's quite a massive thing to learn, I think.

I'd go on the train to castings, changing from my school uniform on the train. I carried on like that for a few years, getting jobs in bits and pieces.

I think if you look down the road for Twitter, we would like to be a company - a service - that is used by billions of people around the world in every country in the world because we feel that the power of Twitter is that it brings people closer to each other, to their governments, to their heroes, etc.

In 1994, after four years of talking about travel on my first show, I realized I knew so little about the world - I knew so little about myself. I decided to quit my job and pursue a postgraduate degree in New York.

The good thing with 'Insidious' and 'The Further' is that it's so nebulous, this supernatural world, that it allows you to bend things. There's a lot of room, it's very malleable, like how in the second film we had a lot of time travel.

Absolutely the worst thing about this job is the travel and being away from family. I have a wife and three wonderful children, the kids are all active in sports and it's very difficult to up and leave and miss them growing up.
