In another coup for Brandeis film studies chairwoman Alice Kelikian, adult film star Sasha Grey is set to visit the Waltham campus this month. The 21-year-old porn star is coming to screen Steven Soderbergh's new film, "The Girlfriend Experience," in which Grey plays - wait for it - a prostitute. The film, which won raves at a test screening at the Sundance Film Festival, is having its world premiere April 29 at the Tribeca Film Festival. Grey will be at Brandeis the very next night, and will do a Q&A with film industry analyst and Brandeis alum Scott Feinberg. Grey is just the latest high-profile actor or director or writer to screen their work at Brandeis. In the past year, Kelikian has hosted Richard Jenkins, Melissa Leo, Michael Shannon, Kate Beckinsale, Alan Alda, Brian Goodman, Mark Ruffalo, Errol Morris, Werner Herzog, Barbet Schroeder, and "Friends" creator Marta Kauffman, who, we're told, will be coming to Brandeis soon to teach.
