Justice League Trailer Breakdown: 28 Things You Must See
21. When Barry Met Bruce
A lot of the trailer, inevitably, is devoted to Bruce Wayne telling Wonder Woman who the characters are, and her recipocrating - this is clearly not in the film (at least it's not them talking to each other), because that would be some horrible clunky exposition. But for the purposes of the trailer, it's absolutely allowed.
Next on the list is The Flash, so we get another look at the Comic Con footage of his lair, including the Easter Egg that he's watching Rick And Morty among lots of other things. The kid's got taste. He also appears to have put his costume on a skeleton, immediately inspiring parallels to this iconic shot...
You have to wonder how long Bruce was just sitting there creepily in the dark with his legs crossed.
And once more we get to see Bruce testing out The Flash's powers by attempting to kill them. Hopefully this was the first guy he thought was Barry Allen...
