In the Wild Cards universe, director Roman Polanski's 1974 movie "Chinatown" is instead "Jokertown". In both versions, the protaganist is portrayed by actor Jack Nicolson. Polanski based his movie on a 1958 encounter between Chop-chop and Fleur van Renssaeler
In 1958 Chop-chop arranged for Fleur to get an illegal abortion. In exchange she tells him about an arson plot to burn down Jokertown. Chop-chop enlists help from two jokers, reputed to be really tough, to help stop the arson scheme. A brief mention of it in the newspapers leads to the deaths of a reporter and Fleur's father (Congressman Henry van Renssaeler).
