The decision follows the shooting rampage at a midnight screening of “The Dark Knight Rises” in Aurora, Colorado on Friday which left 12 people dead and dozens more wounded.

Warner Brothers Switzerland said there would be no special events at the Zurich and Geneva premieres but that the studio decided not to cancel the screenings so that fans could see the film, Swiss news agency ATS said.

Ticket-holders will have their bags searched at the studio’s request in line with security measures imposed globally after the Colorado shooting.

The Swiss premieres are being staged on the same day that the suspected gunman James Holmes made his first appearance in court in Colorado.
