A new teaser for Zack Snyder's Justice League shines the Bat-signal on Ben Affleck's Batman.The clip begins with a shot of Batman standing atop a gargoyle as lightning strikes and rain cascades down toward the camera. We're then given voiceovers from the likes of Cyborg, Alfred, Wonder Woman, Darkseid, Lex Luthor and The Joker. Perhaps most notable, though, is the baritone voice of Harry Lennix's Calvin Swanwick, who's been confirmed to actually be Martian Manhunter. "I have a stake in this world, and it's time I started fighting for it," he says. Meanwhile, we're treated to new shots of Batman's armored tank and Superman, black suit and all, helping the Dark Knight to his feet.RELATED: Zack Snyder to Receive the First Valiant Award From the Hollywood Critics Association

I think that that's kind of the way I see it – that they have the same voice," Snyder said of Swanwick.
