Harvey Weinstein then wanted the film to open on December 25, 2002, but a potential conflict with another film starring Leonardo DiCaprio, "Catch Me If You Can" produced by DreamWorks, caused him to move the opening day to an earlier position. After negotiations between several parties, including the interests of DiCaprio, Weinstein and DreamWorks' Jeffrey Katzenberg, the decision was made on economic grounds: DiCaprio did not want to face a conflict of promoting two movies opening against each other; Katzenberg was able to convince Weinstein that the violence and adult material in "Gangs of New York" would not necessarily attract families on Christmas. Of main concern to all involved was attempting to maximize the film's opening day, an important part of film industry economics.
