Even though it was one of the highlights of Warner Bros.’s Hall H presentation at San Diego this weekend, the studio has decided not to release their preview of Zack Snyder’s upcoming Batman v Superman: Dawn of Justice.

Variety reports that the footage shown at the panel, which included shots of Henry Cavill’s Superman and Ben Affleck’s Batman glowering at each other, will be kept under wraps for the time being.

The brief glimpse at the movie has already triggered speculation over the cause of Superman and Batman’s feud—is Batman disappointed in the destruction Superman wrought at the end of Man of Steel? Is Wonder Woman somehow involved?

Apparently, only those present in Hall H that day will have even the faintest clue. “That’s just going to live in that hall. We’ll post extended trailers and stills, but that presentation, that was just for those fans,” said Sue Kroll, president of worldwide marketing and international distribution for Warner.
