As Morgan Spurlock, director of Super Size Me, tucked into a full English breakfast, he talked about the Oscar-nominated film, how its success has surprised him and what he has in common with Brad Pitt and Hugh Jackman.

Growing Up: I grew up in West Virginia, a state that's very rural, just around everyday regular people. I think having that upbringing really has helped me to look at people in a different way than a jaded New Yorker which I now am. I'm officially a jaded New Yorker! I grew up in a house where my mother would cook dinner every single day. And she wasn't a stay at home Mom, she was an English teacher - she would get up in the morning, make me and my brothers breakfast, go off to school, come back and cook dinner as well. And we never ate out. We never went to fast food places. If I asked my Mom, "Mom, can't we go to a fast food place?" she'd say, "No, we're going home and you can eat food there". She was very militant about us not eating out.

The Inspiration Behind Super Size Me: I was sitting on my Mom's couch, it was Thanksgiving, this magical day of gluttony where we just stuff ourselves with food and I was channel surfing when I came to the story about these two girls who were suing McDonald's. And the more I started hearing about it and the way McDonald's markets to kids, the way that they target children from such a young age with the toys and the playgrounds and the way they manufacture their food, the more I got interested. How there are so many ingredients in something as simple as a French fry or a chicken McNugget. I said "You know, I may not agree with the lawsuit, but there's definitely the basis here for an argument. A spokesperson for McDonald's comes on and he says "You can't link our food to these girls being sick. You can't link our food with these girls being obese. Our food is healthy. It's nutritious. It's good for you".

And I'm sitting there "Hold on a second, if it's that good for me then shouldn't I be able to eat it for 30 days straight with no side effects? Shouldn't I be able to live the all-American Dream of over-eating and under-exercising and be fine?" So then I turned to my vegan girlfriend who was sitting next to me on the couch and I said "I got a great idea for a movie!" and she goes "You're not going to do that. There's no way I'm letting you do that" and at this point I was already running through the house, I was so excited! And I picked up the phone and I called my friend Scott who was the director of photography that worked on the film and I told him about the idea. And when he stopped laughing, he said "Wow, that's a really great bad idea". And I said "Yeah, let's do it"!

McDonald's: We had no idea what would happen with McDonald's. All the time we were making the film it's like a eight hundred pound gorilla sleeping in the corner. How many times can you poke it with a stick until it wakes up! And says "You better stop poking me with that stick. You better stop!" They knew I was making a film about fast food and obesity. I called them and said "We're making a film about this. We wanna talk to you" And I think that it wasn't until we got invited to Sundance and the festival programme hit the market when they said "Hold on now, what's going on?"

And I am positive, they had a slew of people at Sundance who came to see this film. There were people who came up to me in the first two to three screenings who said "Do you know there was a guy outside offered me five hundred bucks for my ticket!" Who in the hell's going to pay $500 to see a movie at Sundance? Ah, it's somebody who has to, who really has to see this movie. So I'm sure that they had their little 'McTeam' lawyers that were there. And publicists who came to see the film, who watched it and who took copious notes and went back to, McDonald Land and reported their findings.

And they said "Okay, how can we deal with this?" Because people ask "Well, why didn't they sue you?" Just like here in Britain with the McLibel trial. This is a company that has used the Courts for a long time to solve a lot of problems but why didn't they with this case? I think that coming off of McLibel, coming off of the lawsuit with the two girls, they really realised that this was something they wouldn't want to fight in court, but they should really fight in the court of public opinion. They should let the people decide and people are never going to stop buying burgers, and I don't want people to stop buying burgers. I just want people to start thinking about how many burgers they're buying.

Reaction to the film: It was so great, we played in towns that would never show a documentary. A friend of mine called me from Dallas, Texas, he went to see the film, and this was a great call. He said "First up I saw your movie. Yeah it was pretty good. But what really impressed me was that the cinema's showing three movies; Van Helsing, Troy, and Super Size Me. So it's Hugh Jackman, Brad Pitt, and you!" And I, I said "That's pretty fantastic!" And then he said, "Hold on, it gets better, it was a Friday night, 9 o'clock, packed, sold out. Half the audience were teenage kids. I couldn't believe how these kids connected with the film". And to me that's just so inspiring to hear that. To think that kids are actually going to see this film I mean, I'm blown away by that still.

Being nominated for an Oscar: I was sitting in New York the day of the Academy nominations and just couldn't sleep all night. It was like every Christmas you could imagine - you're just waiting to go open the toys. Finally Alex and I get up, we have some tea, they do the twelve announcements of the categories but don't announce what the documentary nominations are. So we run to the computer, we go on line and we saw that we got nominated for Best Documentary. And we just started freaking out, we're screaming, we're crying. It was so exciting. And I got on the phone immediately and started calling everybody who worked on the film and told them all to meet me at this restaurant in New York City and so at 9.30 in the morning, we're having champagne breakfast at this restaurant. I'm just on the phone all day long talking to my family, my Mom, every person that I loved in the world to tell them. And God, it's incredible, absolutely overwhelming. The idea that this one film could just really accomplish everything that I could have ever hoped for and beyond. It's just completely humbling to think what, what this film has done.
