Details of the project are being kept under wraps beyond that Wiig and Mumolo will play best friends who find themselves in over their heads and out of their depth.
The duo received a screenplay Oscar nomination for 2011’s “Bridesmaids,” which grossed an impressive $288 million worldwide on a $32 million budget.
Mumolo recently wrote for Fox 2000 the biopic “Joy,” about the inventor of the Miracle Mop, with Jennifer Lawrence starring. She also acted in “This Is 40” and “Afternoon Delight” and has a recurring role on the NBC series “About a Boy.”
Wiig’s credits include “The Secret Life of Walter Mitty,” “Anchorman 2” and “Hateship, Loveship.” She will next be seen in “The Skeleton Twins,” “Nasty Baby” and “Welcome to Me.”
“We’re very excited to be writing,” Wiig and Mumolo said in a statement. “We will be going into a cave for months to finish. An actual cave. We found one that’s nice and big. We’re putting a couch in there.”
Sony Pictures and Rothman launched TriStar last August as a joint venture.
“Kristen and Annie assured me that the film will be a searing and depressing drama, which is what the world needs right now,” Rothman said. “So we grabbed it. Perhaps more to the point, these two supremely talented ladies are always ahead of the comedy curve and as we at TriStar push for originality, we are lucky as hell to be in business with them. The chance to hopefully make Kristen’s first film as a director is the cherry on top.”
The news was first reported by the New York Times.
