Ben Affleck is in talks to star as an aggressive Yuppie stockbroker in Artisan Entertainment’s “Boiler Room,” sources said. The project, which will be produced by Team Todd, is expected to get a green light relatively soon. Filming could begin in New York as early as mid-November. The project, which was set up this summer (HR 7/2), concerns the high-pressured world of Wall Street “boiler rooms,” where young stockbrokers peddle highly dubious stock to unsuspecting buyers. Sources said that negotiations over Affleck’s involvement are not focused on the lead role of Seth, a college dropout who descends into the world of corrupt stock trading. “Boiler Room” will mark the feature directorial debut of Ben Younger, a video director who also penned the screenplay. The film would be produced by Suzanne Todd and Jennifer Todd of Team Todd.
