Los Angeles ? The surprise blockbuster “My Big Fat Greek Wedding,” the splashy musical “Chicago” and the documentary “Bowling for Columbine” were among screenplay nominees Thursday by the Writers Guild of America.

Nia Vardalos — writer and star of the low-budget “Greek Wedding,” which has grossed $240 million — earned a nomination for a Writers Guild Award for best original screenplay.

Other nominees for original screenplay were: Antwone Fisher for his self-titled, autobiographical drama about coming to terms with childhood abuse; Michael Moore for “Bowling for Columbine,” an examination of gun violence in America; Todd Haynes for the 1950s melodrama “Far From Heaven,” which he also directed; and Jay Cocks, Steven Zaillian and Kenneth Lonergan for “Gangs of New York,” Martin Scorsese’s 1860s epic.

Winners will be announced March 8.
