Even though Justice League's only 31 days into the 111 scheduled for production, Zack Snyder and Warner Bros. still managed to show off a clip from the film at last weekend, on set in London.
The scene opens on Barry Allen (Ezra Miller) entering his dark lit apartment, and shortly thereafter all the lights come on to expose Bruce Wayne (Ben Affleck) sitting there, waiting for him.
“Barry Allen… Bruce Wayne,” Bruce says addressing a stunned Barry Allen. “You say that is if it’s normal to have a complete stranger sitting in my second favorite chair,” Barry responds to several laughs from a few press members that are around to watch the epic introduction.
Bruce proceeds to whip out a surveillance shot, which was Flash's cameo appearance in Batman v. Superman; and continues to question Barry about what he was doing during the footage. Barry responds saying that sure, it's someone who looks exactly like him, but is probably just an 'attractive Jewish boy.'
Bruce undeterred by Barry's expectant reluctance to reveal his identity, chucks a Batarang at Barry, who easily sidesteps the assault, launching the scene into slow motion and capturing that moment when Barry learns Bruce's true identity (and vice versa).
Time falls back to normal pacing, and Barry says, "You’re the Batman,” to which Bruce responds, “And you’re fast.” Then Barry tells him Bruce he thinks that way of thinking about the matter is an “over-simplification.”
Scene closes with Bruce recruiting a very eager Flash, who says he needs and friends, and also asks to keep the Batarang.
