Batman cast appearances cancelled

Warner Brothers Pictures has cancelled appearances by the cast and makers of new Batman film The Dark Knight Rises in Mexico and Japan after a gunman killed 12 people and injured at least 50 others during a midnight premiere in the US.

The studio said actors Christian Bale, Anne Hathaway and Joseph Gordon Levitt will no longer hold press or red carpet events at Mexico City's National Auditorium on Monday.

Premiere events in Paris were also cancelled on Friday following the massacre in Denver, Colorado.

The studio said it would continue with screenings for special guests and promotion winners so as not to disappoint fans.
