Chinese film director Zhang Yimou is being sued by two lawyers for breaking China's one-child policy, in what they are calling a protest against rich people flouting the rules.
Jia Fangyi said that he and Guo Chengxi want Zhang to pay one billion yuan in compensation for the use of public services and as a punishment.
Although Zhang already faces a fine that could run into the millions of pounds, Mr Jia said he did not feel that was enough to deter other wealthy people from defying the regulations.
Zhang, who directed House Of Flying Dragons and Hero, admitted on Sunday having three children with his wife.
People caught breaking China's family planning policy must pay a "social compensation fee" based on their annual income.
