Sandra Bullock will star in and produce “The Lost City of D,” a romantic action adventure that is heating up at Paramount.

Adam and Aaron Nee have signed on to direct the project that has quietly percolating for months. “Lost City” is major priority for newly instated Motion Picture Group President Emma Watts and is being envisioned as a potential reunion for Bullock and Ryan Reynolds, a team-up that yielded the 2011 comedy hit “The Proposal.” There is no deal for Reynolds, who is only loosely attached at this stage.

Akin to “Romancing the Stone,” the movie is described as an old-fashioned star vehicle as well as a screwball adventure featuring mismatched leads, witty repartee and of course, romance.

The story follows a romance author, who learns that a supposedly fictional city she had written about is real. She and the actor who portrays the lead character in her book take a life-threatening journey to find this lost city.

Dana Fox wrote the most recent draft of the script which is based on an idea and treatment by Seth Gordon (“Horrible Bosses, Breaking In”). Gordon is producing via his Exhibit A with Bullock, who is producing via her banner, Fortis Films, and Liza Chasin and her 3dot Productions.

The Nees have helmed music videos and garnered attention with their 2015 indie, “Band of Robbers.” They also nabbed the coveted gig of directing the big-budget “He-Man and the Masters of the Universe” feature for Netflix. Bullock hasn’t been on screens since 2018’s two-fer of “Ocean’s 8” and “Bird Box,” the latter a massive hit she executive produced for Netflix. (SD-Agencies)
