Ben Foster and Kirsten Dunst have signed on to star in Red Light Winter for Parts and Labor Productions and writer-director Adam Rapp.

The story centers on two New York City friends vacationing in Amsterdam. Their friendship is tested when they both fall for the same prostitute (Kirsten Dunst). Katherine Waterston also stars as a woman who also has a romantic past with both men. Mark Ruffalo and Billy Crudup were previously attached to star. Ben Foster will take over Mark Ruffalo's role, an up and coming writer, although Billy Crudup's part remains vacant for now.

Adam Rapp is directing from a screenplay he adapted from his own play. Jay Van Hoy, Lars Knudsen, and Scott Rudin are producing. The producers are eyeing a December or January production start.
