The Producers Guild of America has made headway on its “Producers’ Mark” with another high-profile film: Mira Nair’s “The Reluctant Fundamentalist,” which opens the Venice Film Festival on Aug. 29 with an out-of-competition screening.

The mark — an official designation for those certified by the guild as having performed producing duties — has already been used on Prohibition Era drama “Lawless,” which screened in May at Cannes, and on Rob Reiner’s drama “The Magic of Belle Isle,” which opened last month.

The PGA’s “Producers’ Mark,” a lowercase “p.g.a.,” is given only to producers who request it and who have been certified through the PGA arbitration process; companies remain free to recognize other individuals with the traditional “Produced By” credit as they deem appropriate.

Lydia Dean Pilcher received the official PGA mark for “The Reluctant Fundamentalist” for Cine Mosaic Prods. The political thriller, which does not yet have a U.S. distributor, will also screen at the Toronto Film Festival.

Lucy Fisher and Douglas Wick received the PGA designation for “Lawless” for Annapurna Prods., scheduled for wide release on Aug. 29 through the Weinstein Co. “The Magic of Belle Isle,” released by Magnolia, included the PGA mark for Rob Reiner, Alan Greisman and Lori McCreary for Revelations Entertainment.

The PGA, which has more than 5,000 members, first unveiled the concept in October 2010, with co-presidents Mark Gordon and Hawk Koch touting it as a milestone. More than 150 high-profile producers — including Lorenzo di Bonaventura, Clint Eastwood, David Heyman, Jeffrey Katzenberg, Graham King, Neal Moritz, Scott Rudin and Steven Spielberg — publicly endorsed the concept as a way of bolstering the guild’s decade-long campaign to stop the proliferation of undeserved producer credits.

People familiar with the current situation said the PGA has signed but not yet announced at least two other studios besides TWC and Magnolia. The companies will provide a “Notice of Producing Credits” to the PGA, just as they currently do for awards contenders, but now no later than the commencement of post-production.
