10 people have been shot dead at a Batman: The Dark Knight Rises film premiere in Denver, Colorado, Birmingham Mail said.

The Denver Post had earlier reported that expectations had been at fever pitch in the city, with several cinemas preparing to unveil the film to the public at midnight.

Fans had been queuing for the premiere since 10am yesterday, July 19.

Tickets for a showing at the UA Colorado Center for the midnight showing sold so fast that a 3.30am showing had been hurriedly added.
