It's the weird thing Eton does - you're at school next to lords and earls and, in my case, Prince William, so you end up being used to dealing with those sorts of people.
I do get stopped a bit now and then, but I can go to the supermarket and on the Tube without being noticed. It's usually me that gets starstruck, especially by TV stars.
Ladies and babies, and mortgages, for that matter, can all wait. Acting has done a strange thing to me, though. I often sit there, thinking, 'I love this, but I wouldn't put my daughter on the stage.'
A lot of people think theatre must be much harder work than film, but anything histrionic or superfluous gets seen on camera so you have to work to distil it into a complete sense of what's true.
I'm quite ignorant about fashion and I'm colourblind, so it's all a tad tricky. My only knowledge of that world comes through Christopher Bailey, whom I first met in 2008 when I did a campaign for Burberry that featured musicians, artists, actors and sportsmen.
Making 'Birdsong,' on the one hand you have how prestigious it is and the reputation of the book, which is something that's an extraordinary piece of work. Sebastian Faulkes is a genius. So you feel that responsibility when you're portraying that character that he's imagined and millions of readers have pictured.
If I do a film and have to get naked, that tends to dictate how often I go to the gym. Acting in 'Richard II' on stage was a huge physical workout, so I ended up more toned than I normally am.
I had never been to a fashion show before going to the Burberry show last month. It was an extraordinary spectacle. I was incredibly green and had no idea what an undertaking it is. I also have a new respect for models because they are so close to the front row and must be so self-conscious.
What's really interesting about actors, is that we all have opinions on how people's careers look, but I think you never have any idea of your own, or what other people think of you.
I think all actors have a similar deal. You want some people who understand. Although it looks great - and is great - there are also shoddy moments when you feel really rotten, and when it's going well, you're not allowed to complain.
I'm trying to buy a house and set some sense of roots because otherwise you're constantly chasing one job after another, and you look back and you've had all these very extraordinary experiences with extraordinary people, but there's not a line of continuity to it.
I have this horrific thing where I'm really bad with names and faces. I have an appalling memory. Someone will come up to me in the street and go, 'Eddie!', and I'll try and give myself time by going into overdrive, 'Hey, hi! Nice to see you!' and start a whole conversation because I can't distinguish between who I know and who I don't.
I always try to describe making movies like summer camp, or some holiday where you spend all day, every day with a new group of people whom you kind of love and then never see again.
When I was living in New York, I had this slightly wannabe bohemian existence and took up painting, at which I'm appalling. I also bought several guitars.
As an actor there's a lot of scrutiny and, even when you've had success, it becomes about sustaining that success. A friend of mine described it as a peakless mountain. Even for De Niro there's Pacino and for Pacino there's De Niro.
Most actors hate watching their own films because all you can see is the glaring mistakes, your own tricks and ticks.
Making a film or doing a play are completely different experiences and entirely fulfilling, but completely unique. I also think one complements the other. People often say that theater is about flexing your muscles, and is actually real acting, whereas I sort of disagree.
Everything about filmmaking is incredibly weird, and there's nothing natural about watching yourself on the big screen or hearing your voice. It's that same thing that you feel when you watch yourself on a video camera and you hate the sound of your voice - it's that times 800.
And you can't complain about kissing Emma Watson. Isn't that what everyone in the world wants to do? I've known Emma for a few years. She's this amazing capacity of young and vibrant and brilliant, but also a bright, intelligent old soul.
If you're an English actor and turn up in America, they don't have an opinion about where you sit. They have no idea what auditions to send you to, so they send you to everything.
