The Paris premiere of the new Batman film, The Dark Knight Rises, has been cancelled following a shooting at a midnight screening in Colorado, US.
At least 12 people have been killed and dozens injured in the attack in Denver, Colorado on Thursday night.
Witnesses said a man wearing a gas mask opened fire as movie-goers watched the film.
In a statement film studio Warner Bros. said they were “deeply saddened to learn about this shocking incident”.
“We extend our sincere sympathies to the families and loved ones of the victims at this tragic time,” the statement said.
As well as the cancellation of the red carpet premiere on the Champs-Elysees, the Hollywood Reporter reported that media interviews with the director, Christoper Nolan, and the film’s cast have also been cancelled.
The Paris premiere was due to take place on Friday.
