“The Amazing Spider-Man” producer Matt Tolmach and “Aquaman” scribe Kurt Johnstad have sold an untitled pitch to Sony Pictures based on an original idea from Johnstad.

The plot details are being kept under wraps, with insiders describing the super-secret concept only as a big sci-fi action idea. The hope is that the project can turn into a potential franchise.

Tolmach would produce through his production banner, with Johnstad penning the script.

Tolmach’s executive VP of production, David Manpearl, brought the pitch to Tolmach who, like so many producers in town, wanted to work with Johnstad following his success on “Act of Valor” and “300: Rise of an Empire.” The two then took the pitch to Columbia Pictures president of production Michael De Luca and senior VP of production Jonathan Kadin, who were so excited by the idea that they bought the pitch in the room.

De Luca has been working hard to find more titles and properties for the studio that can turn into franchises, and sees potential in this pitch given the players involved.

As for Johnstad, the scribe has begun to make a name for himself as writer who delivers big action in his scripts, along with classic heroes audiences love to root for. Besides penning both “300” and “Act of Valor,” Johnstad is also set to pen “Aquaman” for Warner Bros., starring Jason Momoa. “Aquaman,” like all other DC properties, is a top priority at the studio.

He is also developing several other scripts including “The Lost Legion” for Warner Bros. and Dan Lin. He is repped by WME.
