"Batman v Superman: Dawn of Justice" is in theaters ... there's only one way you should see the movie: 2D IMAX on a real IMAX screen. Director Zack Snyder filmed several scenes in IMAX 70mm.
And Superman will not even be the first Superman movie shot at least partially in IMAX; Zack Snyder‘s Batman v Superman: Dawn of Justice contained sequences shot with IMAX 65mm cameras.
