Title: 54 (film)
Content:  Based on two short films Mark Christopher made, Miramax Films persuaded Christopher to direct the full-length feature about Studio 54. He had spent five years researching the club and the time period while working on a screenplay. Miramax purchased a partial screenplay in 1995 and developed the script with the filmmaker for over a year. Christopher shot the film in Toronto over two months in the fall of 1997. During the production, a Miramax executive was often present on the set and studio head Harvey Weinstein flew up from New York to give his approval. In the 1998 version, Christopher finished his cut of the film and the studio scheduled the film's release for July of the following year. After initial positive reactions within the company and a test screening in Manhattan, further test screenings in the suburbs disappointed the studio. Audiences found the lead character's bisexuality unlikable and reacted negatively to a kiss between Shane and Greg. They also did not respond well to the happy ending for both of them and Anita. Miramax requested cuts be made and Christopher initially refused.
