Contrary to rumors, J.J. Abrams said “Overlord” will not be the fourth film in the “Cloverfield” series. Instead, the horror film about World War II soldiers who find out the Nazis are using supernatural forces and engaging in gruesome experiments, will be Bad Robot’s first R-rated movie.

“It’s bat shit crazy,” Abrams said in taped remarks for Paramount Pictures’ CinemaCon presentation on Wednesday.

But fans of the popular horror series need not fear. Abrams said that “we’re actually developing a true, dedicated Cloverfield sequel” and unlike the most recent film in the series, which was sold to Netflix, this one will screen in theaters.

The “Overlord” footage lived up to the hype. There’s eerie shots of dead soldiers hanging from trees, genetically modified Nazis, and disembodied and fanged heads. The film follows a band of paratroopers who find themselves behind enemy lines. In a colorful nod to history, the preview contains Paramount Pictures’ logo from the 1940’s.

“Overlord” opens October 26, 2018. The cast includes Jovan Adepo, Wyatt Russell, Jacob Anderson, and Pilou Asbaek. Julius Avery directs the film. Abrams will produce. Bad Robot also oversees the “Star Trek” and “Mission: Impossible” franchises.

Paramount used its time at the exhibition industry conference to debut footage from “Mission: Impossible – Fallout,” “Bumblebee,” and “Book Club.”
