Justice League is only 31 days into an expected 111 of production but, in a move which was likely an effort to remove doubt towards the project, director Zack Snyder and Warner Brothers were ready to show off the first clip from the film this weekend on set in London.

Snyder was quick to point out that the clip shown was not a “final cut” and even pointed out which aspects of it would receive visual effects upgrades as it played but, nevertheless, the scene sent a message: the producers are listening to critics and fans. Mild spoilers for Justice League follow.

The scene starts out with Ezra Miller’s Barry Allen heading into his apartment. It’s dark and seems to be part of what looks like a warehouse. It’s unconventional - high ceilings, looks old, and is powered by a circuit breaker when Barry arrives to flip its switch. When that switch is flipped, dozens of lights and TV screens hanging from the ceiling are turned on. More importantly, Ben Affleck’s Bruce Wayne is sitting in Barry’s apartment waiting for him.

“Barry Allen… Bruce Wayne,” Bruce says to a stunned Barry. “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 the select press members watching. Bruce quickly reveals a print out of a screenshot from the convenience store surveillance footage which served as one of The Flash’s cameos in Batman v Superman: Dawn of Justice. Bruce questions Barry about what he’s doing in the moments caught on camera, but Barry insists, comedically, that is someone who looks exactly like him but is definitely not him - just an “attractive Jewish boy.”

Bruce is obviously not convinced, as he throws a Batarang at Barry, also throwing the scene into slow motion with a couple flashes of light and wind accompanying the scene. Barry steps to the side, looking at the Batarang which would have otherwise hit him in the face, and realizes Bruce Wayne is Batman. He catches it (the Batarang was not added into this part of the scene yet so Miller merely performed the motion of catching it) and looks back to Bruce. Time reverts to normal speed and Barry tells Bruce, “You’re the Batman,” to which Bruce responds, “And you’re fast.” Another comedic dime rolls out when Barry tells Bruce he thinks that way of thinking is an “over-simplification.”

Bruce reveals to Barry that he’s recruiting people like him and Barry signs up immediately, with zero hesitation. After a pause, he tells Bruce he “needs friends” and asks to keep the Batarang.

Justice League hits theaters November 17, 2017.
