DreamWorks Animation’s upcoming CG animated feature, Rise of the Guardians, has recently received the special Producers’ Mark credit courtesy of The Producers Guild of America, according to a report by Variety, making it the sixth feature so far to carry the certification.

The notification, which is represented by a lowercase “p.g.a” that denotes individuals certified by the guild as having performed producing duties, was first introduced at the Cannes Festival when it appeared on the period piece, Lawless. It’s also in the credits of Mira Nair’s The Reluctant Fundamentalist, David O’Russell’s Silver Linings Playbook, Rob Reiner’s The Magic of Belle Isle and indie comedy-drama Lonely Boy. The producers of Rise of the Guardians who received the certification are Christina Steinberg and Nancy Bernstein.

The Producers’ Mark is awarded only to producers who request it and who have passed through the PGA arbitration process. Companies are free to recognize other individuals with the traditional “produced by” credit as they see appropriate.
