Sometimes I feel that in religious content, religious drama, it's almost told like a tale, like an account of facts, and in 'A.D. The Bible Continues,' it's drama, it's real drama that we like to see on TV today, seeing the characters struggle and doubt and be completely in conflict with each other, kind of like 'House of Cards.'

I arrived in Los Angeles on the Monday, had a call from my agent to say they wanted to see me for 'Dallas,' made an audition tape at my friend's house in L.A. the same day, and had the job the following Monday.

I got the call to play Tony Manero in 'Saturday Night Fever' in Madrid, a role I'd always wanted, as it's such a well-constructed show, and my background is in musical theatre. I'd been travelling back and forth between London and Spain for auditions and had been borrowing money from friends to do it.

There's a lot of actors that I admire because they can just switch one second into the character. Then, they go back to jokes, and then they're doing something really dramatic. I can't do that. I have to really focus.

Even though my work is whimsical. I have a very serious job. I cry more than I laugh.

I think what's really going to happen is we're going to have a lot of different kinds of phones when our industry grows up - some that are just plain, simple telephones. In fact, my wife and I started a company, and she designed the Jitterbug, which is just a simple telephone.

Career is too pompous a word. It was a job, and I have always felt privileged to be paid for what I love doing.

I wanted to create a toolkit which I would have wanted as an entrepreneur to use these principles of psychology in product design. Some startups totally forget the trigger. In some, the action is too complicated. Others don't have a variable reward, which maintains mystery.
