Law, who now divides his time between Australia and China, said he and his colleagues tried various ways to portray the PM. "The puppets were just heightened versions of reality, so there were three Thatchers: one that talked to you as if your dog had died; one that shouted at you and a foaming-at-the-mouth one. There never really was a smiley Thatcher. What would be the point?"
In one famous scene set in a restaurant, a waiter asks Thatcher, who is treating her ministers to a meal, what she would like to eat: "Steak, raw please," comes the reply. "And what about the vegetables?" asks the waiter. "Oh, they'll have the same as me."
The scene mocks Thatcher's Cabinet colleagues as being weak and ineffectual, and while Law admits he was worried about glorifying Thatcher, he said he tried to be fair to both sides. "We dished out the same stick to everybody, including (opposition leader Neil) Kinnock, but at least we tried to get it right."
Thatcher left Britain in a worse situation than before she came to power, Law believes. "I believe she had a strong effect on what happened here. She threw a lot of people to the dogs and you're seeing now what she actually did. I'm still angry about that now.
"When you think of how our parents worked, when you could go to the doctor without thinking about the money. People like myself got half an education. I went to art school from a working class background without qualifications simply because I had some talent. Try doing that now. All of that has gone, and you know that was her aim. It's what she wanted.
"I don't have any answers like lots of other critics. But take a look around you. The people who came after inherited the mantle of Thatcher: her heirs ... the bitch she left behind was Tony Blair ... and now we have a huge underclass. Give up on consensus politics, and the notion of educating everybody properly. F**k 'em, basically."
