2012 is already shaping up to be Abigail Spencer's breakthrough year. The supporting actress, who has scored small roles in Cowboys and Aliens and This Means War, was just signed to star in Joss Whedon's soon-to-shoot supernatural romance In Your Eyes. And now THR has uncovered the will-be leading lady has also made the leap to screenwriter.

Spencer, who is most often recognized for her work as Don Draper's mistress on Mad Men, has penned a romantic comedy called Wrong Number about a couple whose meet-cute happens during a misdialed call. The film, which will be AnnaRose King's feature-length directorial debut, is the first of six co-productions between James Franco's Rabbit Bandini Productions, Victorino Noval Productions, and Edward Bass Films. Spencer will act as a producer as well as star, playing a married woman who is driven by grief over her father's death to recklessly pursue the stranger from a wrong number. The cast also includes Andrew Leeds, Matt Gould, Griffin Matthews, Camille Chen and Eric Roberts, but there's no word yet on who will star opposite Spencer.

Franco and Spencer met during production of Oz: The Great and Powerful, in which he had landed the title role, and she, the supporting role of May. On set, the pair's conversation turned to Spencer's script, and Franco grew intrigued. He confessed:

“I’ve been making some of these smaller movies with people from NYU and other students and I thought I could be helpful [in making Wrong Number happen]…It’s a romantic comedy in a way, and I didn’t think I would be that into a romantic comedy, but I think structurally it’s unlike anything I’ve seen.”

While there was a time I'd be surprised to hear James Franco is producing a romantic comedy, it's become hard to imagine a project the multi-faceted entertainer won't tackle.

Wrong Number is set to shoot this spring.
