Russell has a mission, and it's to upset the apple cart
In the film, Russell also doorsteps the Daily Mail's owner Lord Rothermere, visiting his house and asking him to explain his non-domiciled tax status. Watch him in action here...
At the screening, Russell promised the crowd he's not done now he's finished his book and the film, there's more where that came from...
This week, Michael Winterbottom spoke to HuffPostUK about making the film with Russell, and the surprise he got when they went to the City of London to film the bankers that were the subjects of their wrath.
“When we were filming in the banks, even the city workers would come up and ask for a hug,” said Michael. “These were the people we were railing against in the film, but they didn’t seem to mind. Russell has a strange attraction that crosses over these boundaries.”

"At least, on a personal level he was sort of funny. I don't have a very good memory for hatred, so every time I see a picture of him now, cos he looks a bit like a monkey, I think 'aw, cute'. I forgot all the wars he started.[Brand called George Bush a 'retarded cowboy' at the MTV Awards in 2008]"I said, in America, it was nice you let him be president, because we in England we wouldn't give him a pair of scissors. And if I'd have said that in England, that's funny. "Next day in America I had police round my house because people were trying to kill me. For that!" (credit:AP)

"I like how he was serious about non-violence. It is genius because it is a paradigm breaker. If you are at protest, without being violent, they can't nick you. Also, he was a very disciplined man, and he said the only thing he hated more than violence was cowardice, so he was prepared to get the shit kicked out of him whenever required. You can't argue with that."
Margaret Thatcher(08 of11)

She broke down our most treasured institutions, drove a knife through the socialist heart of this country, ripped up the North, made our kids think it was OK to be selfish, got everyone to sell off their council houses. It was a terrible, terrible thing. (credit:PA)

"It's a shame, I felt pumped for a while [after he was elected]. I thought it was better to have a black president than a white one, moving in the right direction. But it is a shame. These people are meaningless, interchangeable. It's not much different in America now, but I prefer him to Bush." (credit:AP)

People who are prepared to put themselves inside." (credit:AP)

"I don't know who that is."[The President of Syria]"Um, I am not sure about that, he seems a little slippery, I am not into his whistles, but I don't know very much. And it seems like others don't know much either. All I know is when I see those images coming out of Syria, it's terrible. You do want to help, but it has to be refugees, humanitarian stuff, not starting more wars or arming folks." (credit:AP)
