A number of years ago, a development executive named Franklin Leonard published a list of Hollywood's best liked unproduced screenplays and cheekily called it The Black List. (Leonard is black.) I met Leonard at the Toronto International Film Festival this year. He's a smart, young guy who recently left Universal to go to work for Will Smith's company. But he's continued to produce The Black List and this year's was just released.
The loglines for the scripts are interesting reading. Many, if not most are based on true stories. Very few comedies. Almost all are in development with a studio. All are represented by an agent.
Last year's list included Aaron Sorkin's The Social Network, so this is not a list of unproduced writers, just screenplays.
