If we didn't want to upset anyone we would make films about sewing but even that could be dangerous. But I think finally in a film it is how the balance is and the feelings are. But I think there has to be those contrasts and strong things within a film for the total experience.

It is very easy to make clear what you want a film to say but I did not wish to engage in overt propaganda even for the right cause. I wanted to create an experience through the films something where people could have the freedom of their own response to them.

It never occurred to me that I'd be on a television show or in feature films but when those came into play my dreams changed along the way.

If dreams are like movies then memories are films about ghosts.

In our increasingly secular society with so many disparate gods and different faiths superhero films present a unique canvas upon which our shared hopes dreams and apocalyptic nightmares can be projected and played out.

One of the best animated films I've seen come out of Disney was the Tarzan movie. I wasn't crazy about the story or the design on Tarzan's face but the traditional animation was spectacular.

I'm a fan of horrors. I love the ones that make you jump. My girlfriend hates it. I've been dating her for one-and-a-half years and I'm crazy about her but she's terrified of horror films. Not the cute 'Will you hold me?' way but she's weeping. With 'House of Wax ' we'll be sleeping and I'll go to the bathroom and she's sitting up waiting for me.

Comedy was why I got into acting the first place. Peter Sellers was a huge influence on my wanting to act. I grew up with him and found him hysterical. The Pink Panther films were an inspiration from my earliest childhood days when I was watching them with my brother and my dad.

I have a theory that I really want my kids to know - the only coloration that they make between dad being in films and reality is just a lot of people doing a lot of hard work.

My dad had a commercial film company so he had a videotape player before anyone. So he got Mel Brooks movies or Citizen Kane or some classic old movies. And every summer the revival house in Evanston would show the great films from the '50s and '60s and '70s.

Working with my dad was such a gas. We approached the work in a similar way. We only made two films together when I was an adult Tucker and Blown Away but it was so much fun to play with your parent like that.

Now that I've got some films under my belt I have the courage of my convictions regarding acting. It gives me a leg to stand on.

I've done four other films since 'Submarine ' so that's quite cool. It's just good to have people respect your work I've never had that before. Yeah my life has changed crazy. I'm a kid from a small town in south Wales I play my Xbox usually and all that sort of stuff and it's a whole new world.

My role in 'Legally Blonde' was really rewarding because I had so much fun working on the movie. I've had really rewarding experiences on tiny low budget films that you'll never see but where I had a cool time creating characters as well. I love almost all of the characters I've played.

The frustrating part of it is that you're generally known for what you did last. I've had the privilege of doing some very cool independent films that a lot of the time the general public doesn't see unless you're at a film festival or you're into that kind of movie.

Like I said about Freaked people tend to find these films and I think that in the end the cool thing about a movie is that it can be sort of burnt temporarily but then it's burnt into the fabric of your culture.

Films are really cool because every couple months or however many times you can get a job because there's a lot of luck involved in that you're playing a different character.

Period costume films are fun to discover but they're not relatable. It's more 'Wow that's cool - did it really look like that back then?' Whereas with a comedy you're like 'Yeah that's me that's my friends.' No matter what I want people to relate.

And of course I've got kids of my own now and they love me being in the Harry Potter films. I'm now part of a phenomenon. You become incredibly cool to your kids and you get a young fan base. So you became the cool dad at school. You're suddenly hip.

The nerds are the ones that make the films and do loads of other really cool stuff in their life.

Sci-fi films are the epic films of the day because we can no longer put 10 000 extras in the scene - but we can draw thousands of aliens with computers.

Computers in classrooms are the filmstrips of the 1990s.

The thing I've come to learn is that what's great about small independent films is the intimacy and the communication that occurs when you're making them.

As far as I was concerned either I was a homosexual or I wasn't so making films would change nothing.
