Working with people like Jennifer Aniston and Jason Sudeikis is such a blessing because I've watched them a great deal. I grew up with 'Friends' and always aspired to work with someone from that cast. Jason is just such an amazing comedian.
Sometimes I've been more emotionally disturbed by the experience of shooting a comedy than a drama. After 'We're the Millers', I think playing this battered loser who's confidence was at zero for 90 percent of the movie, I did genuinely feel that way.
I wasn't good at anything at school, and acting was the only thing that I really loved doing and was interested in. It was kind of like my only option. For me to get opportunities in acting is so fortunate. I found something I loved doing and wasn't terrible at; it was quite nice.
It was incredibly daunting for me to go from 'Son Of Rambow' to 'Narnia' because of the natural jump that there is that is dictated by budget, and the number of people working on it. Even though a lot more people saw 'Son Of Rambow' than we expected, a lot more people were always going to go and see 'Narnia'.
One of the challenges obviously with doing an accent from a time period early in history is that there aren't recordings. You would never really get the opportunity to hear exactly what you were shooting for.
The transitional period is tough. You can find yourself too old to play high school roles but too young to play the leading man. You have to be quite smart about how you present yourself. Your public image reflects your range.
I hate the school of thought that says work is work and that you have to be unhappy at work because that's what work is. I totally respect the fact that not everyone has the choices that I have, and that some people have to work jobs that they don't like because they don't have any other options.
My teacher told my mum, 'I think William has dyspraxia,' and Mum asked what that meant. She said, 'Well, if I put a chair in the middle of the room and asked every child in the class to walk around it, William would be the only child in the class to walk into it.' Mum was like, 'Yeah, that's my boy'.
I didn't want to be behind a desk. I didn't want to do a normal job. I had made my mind up. I became despondent prematurely. I had my mid-life crisis when I was 16. I suppose I'd agree with that. But acting has helped me develop a lot in my private life.
I actually found 'We're the Millers' one of the toughest, if I'm honest, least fun experiences of my life, which is weird. It was such a huge opportunity for me to work with the people I worked with and I feel grateful to be a part of that, but it kind of messed me up.
It may sound strange to say it of someone so famous, but I think Leonardo DiCaprio is underrated, particularly from an awards perspective. He is a very versatile actor. He started very young, and 'What's Eating Gilbert Grape?' is one of my favourite films.
Seeing the actual 'The Chronicles of Narnia: The Lion, the Witch, and the Wardrobe', I absolutely loved it. It became one of my favourite films. It was a real Christmas classic, and it was one of the most popular films ever in British history.
My problem is I'm not talented enough to do everything, but I want to do everything. I'm like, 'Oh God, I wish I could dance! Oh God, I wish I could rap!' I can't be a rapper, and I'm sure as hell not going to be able to dance for a living, but I want to do it all, you know?
I think the one thing that I've experienced with American films is just that the size tends to be so much bigger, the budgets have been bigger, the size of the sets have been bigger, the number of people working on them is bigger, but that's not to say that I haven't been able to get close to people or develop good relationships.
I think we have a responsibility to shape the zeitgeist with the movies we put out there. Because 'After Earth' isn't going to do it. 'The Expendables 3' isn't going to do it. You could make one million amazing films for the amount of money they spend on those films. I get frustrated.
I hate going into the audition room. I find it the most nerve-wracking, inhumane experience, and I think it's such an inhospitable environment to give an honest account of the character and, I guess, your ability.
What's hilarious is people taking photos and they think you don't know. It's the funniest thing I've ever seen. Like taking a picture of their mate for example but about three foot wide of their face - and the flash is on half the time!
It's difficult to tell whether people are looking at you because they recognise you from your work or just because you're 6 ft. 3 in. and have the eyebrows of Satan. It's difficult to distinguish between the two.
Drama is what I'm really obsessed by. It's what gets me up in the morning, what I live for. But I'll always have a love for comedy because it was my first opportunity, and I associate it with my best friends, who I made during 'School of Comedy'.
I think I'm slightly OCD. I'll be desperate to get a part, but as soon as I do, the sense of pride wears off almost immediately, and fear of not doing a good job sets in. I'll think, 'This is a dream come true,' and then, 'It's not OK until I get a good review.'
This is a business, and no one enters a race not to finish first. I wouldn't say I'm in it for the competition, but I'm certainly not just in it to coast along. I want to be the best I possibly can be.
