Warner Bros. has signed David Katzenberg and Seth Grahame-Smith to a two-year first-look deal via their KatzSmith Prods. banner.

Studio announced the signing Tuesday, citing Grahame-Smith’s work on penning the upcoming “Dark Shadows,” with Johnny Depp starring and Tim Burton directing.

“We first got to know Seth through his fantastic work on ‘Dark Shadows,’ and it immediately became a priority to expand our relationship with him,” said Warner Bros. production prexy Greg Silverman. “Seth introduced us to David, who greatly impresses us with the vision for KatzSmith from the very first meeting. We firmly believe in their talents and are extremely excited to welcome them to the Warners family.”

Warners currently has 34 producing deals, far more than any other studio.

Grahame-Smith also wrote the novels “Abraham Lincoln: Vampire Hunter” and “Pride and Prejudice and Zombies” and adapted the Lincoln project for Fox, due out June 22.

Katzenberg and Grahame-Smith are developing a reboot of “Beetlejuice” for Warners, though the studio hasn’t closed deals for the rights. Burton directed the 1988 original starring Michael Keaton.

Katzenberg is the son of DreamWorks Animation chief Jeffrey Katzenberg. He and Grahame-Smith exec produced the series “The Hard Times of RJ Berger.”
