I’ve worked with lots of different styles. I did a couple of low-budget features using real people to act as themselves and I had embarked on a feature, The Catastrophist , using actors, and there was this endless process of getting it off the ground, so I thought it would be good to recharge my batteries and go back to my roots. Plus there were other things. There’s always an interaction between the personal and the work. My father had just died and was anxious to go and do something on the spur of the moment. The thought of going off to Alaska was actually rather appealing at that time.
Many of your subject seem to see themselves as victims, even when they’re not. Is that fair?
I think that’s true. [Palin] very much reminded me of Margaret Thatcher, who in her later years would only allow herself to be interviewed by designated interviewers. Sarah Palin was exactly like that. She only would be interviewed by Fox News. I think the paranoia you’re talking about comes with power. It’s somebody with an absolute philosophy who isn’t interested in people who disagree with them. None of them were interested in democracy and open discussion, or a belief that several brains looking at a problem will come up with a solution better than your own. They’re all very reluctant to embrace criticism and regard it as a destructive thing.
How big a role do you think Palin’s parents play in her life?
I think she’s incredibly close to her parents. Her father was her science teacher and track coach. Apparently as well as being somebody who was rightfully very popular as a teacher – he had all these mammoths and dead animals – he was incredibly brutal to people. I don’t think Sarah was a natural athlete and she was always trying to get his respect and approval. Basically, nothing was ever good enough. It’s interesting she married Todd, who was the best basketball player, the one star they had. She was always devoted more than anything else to impressing her father and having him on board, and he’s somebody who absolutely sees the world in black and white tones: you’re either with him or you’re against him.
Why are those who loved her so reluctant to embrace Mitt Romney?
Well, firstly he’s a Mormon. He’s not a fundamentalist Christian. He doesn’t embody all those fundamentalist positions. He’s changed his position on abortion, which is a fundamental thing for them. He’s changed his position on things like health care, so I think he’s basically toadying to the extreme right because he knows he needs their support to carry the Republican party in the election. But no one really believes that he’s a dyed-in-the-wool fundamentalist in the way Sarah Palin or Michele Bachmann are. I think Romney is regarded as an outsider.
I see she has a TV show now.
She’s been under contract with Fox for some time. I think Murdoch regarded her as a rising star and believed in a lot of the stuff she was saying. Believed in her populism. That she was a great demagogue and had a loyal following. Maybe believed mistakenly that she was going to be vice-president and that his empire would benefit from her philosophy...
How many of you were there working on the film?
In Alaska there was a researcher who was looking at archives, contacting people and making phone calls, then somebody doing all the technical side of things – film making has become more and more technical: downloading footage, coming along on shoots, keeping everything going – and then Joan Churchill was the camerawoman and I was doing sound. So there was basically four of us. In post-production we probably had another three researchers. The Sarah Palin film was a frustrating film and it was very hard to get footage for stuff. It required more people than normal.
Do you think people have started to distrust you?
I think certain people do. I guess Sarah Palin obviously did. I think when I was doing things like Aileen  or Kurt & Courtney , Biggie and Tupac , everything was fine, but I think probably right-wing politicians and those kinds of people do distrust me. And of course everything has got more difficult with the internet. You can find out what somebody’s done and how they’re perceived.
What are you up to now?
I’m just finishing an undercover film I did with the same journalist who I worked with on Ghosts, Hsiao-Hung Pai . She did a stint as a housemaid in a Chinese brothel in Bedford. Based on those studies we did another undercover film which is called Sex in Bedford and should be out some time in the new year.
Did you manage a cameo?
I did actually visit once, but no, I didn’t make a guest appearance as an evening customer.
"Sarah Palin: You Betcha!" and the "Nick Broomfield Documentary Collection" are available now on DVD from Universal Pictures (UK).
