A day after the tragedy at a “The Dark Knight Rises” screening in Colorado, Warner Bros. has officially cancelled key portions of the pic’s international press tour.The studio, which had already scrubbed Paris premiere on Friday, made the announcement Saturday afternoon. It will still hold screenings in Mexico and Japan but without the red carpet festivities. “Due to the tragic events in Aurora, Colorado, Warner Bros. Pictures has cancelled the previously scheduled personal appearances by the cast and filmmakers in Mexico and Japan on behalf of The Dark Knight Rises,” Warners said. “However, in an effort not to disappoint the dedicated fans of the film, we will proceed with our previously scheduled special screenings for invited guests and promotional winners.” The studio had been expected to cancel next week’s premieres and press junkets in the wake of a gunman killing 12 people and wounding more than 50 others at a midnight screening in the Denver suburb of Aurora, Colo. The red-carpet premieres would have included stars such as Christian Bale and Anne Hathaway along with screenings of the film.
