While the trailer for next year’s superhero showdown Batman v Superman: Dawn of Justice is supposed to be kept under wraps in the U.S. until after its IMAX premiere on Monday, a handheld video of the trailer has already made its way online.

According to Variety, copies of the video — which appears to have been shot in a theater in Brazil — have been pulled by YouTube, but other services, like vidme, are still hosting the shaky 2-minute clip that features Ben Affleck in his first go as Batman and Henry Cavill taking his sophomore shot at playing the Man of Steel.

The movie is scheduled to premiere in March 2016.

Studios and exhibitors love to use exclusive trailer premieres as a way to lure consumers into going to theaters, but it doesn’t always work. Last year, the trailer for Marvel’s first Avengers movie leaked in advance of its theatrical debut, leading the studio to just go ahead and release an official version of the trailer.
