Batman is in for a nasty surprise. In a new clip from "Justice League Dark," Deadman reaches out for the Dark Knight's help, but he may just cross a boundary or two in order to do so.

The clip opens as Bruce Wayne prepares for a shave. As soon as he touches his razor to his face, though, an unseen entity creeps up behind him, and he appears to be completely oblivious to its presence. When he becomes aware of it, it startles him enough that he cuts his cheek, and the pain causes him to look away for a brief moment. When he looks back up, he finds a name scrawled in the fogged up mirror: Constantine.

The branding doesn't stop there. When he ducks out of the bathroom and back into his bedroom, he's greeted with even more supernatural graffiti. In addition to Constantine's name, strange symbols appear all over his walls, scrawled in a deep red color that looks ominously like blood.

According to the description of the clip, the messages were left by Deadman: "This is an all-new clip from 'Justice League Dark' that features Bruce Wayne ... shaving. And then suddenly discovering he's had a stealth visit from Deadman, who has left a message with no room for interpretation."

In “Justice League Dark,” Batman will operate as a sort of POV-character to serve as an entry point for viewers unfamiliar with this magical side of the DC Universe. As such, he’ll be a bit of a Doubting Thomas in the animated film.

The clip originally debuted at last year’s New York Comic Con. “There’s a lot of magic, there’s a lot action — it’s superhero stuff with a lot of magic spells,” producer James Tucker explained at the time. “Basically, I asked myself what I would do if I made a ‘Harry Potter’ movie, and that’s basically this film,” added director Jay Oliva.
