Midnight Movie Massacre: Studio saddened by 'shocking' scene at movie's midnight showing

The studio behind "Batman: The Dark Knight Rises" expressed their shock and extended their condolences to the victims of a mass shooting at one of the film's midnight screenings.

"Warner Bros. and the filmmakers are deeply saddened to learn about this shocking incident," the studio said in a statement. "We extend our sincere sympathies to the families and loved ones of the victims at this tragic time."

In a phone interview with FOXNews.com Friday morning ‘Dark Knight Rises’ producer Michael Uslan also expressed  his deep sadness for those lost in the tragedy and their loved ones.  He said he would be suspending his media appearances out of respect for those killed and injured in the tragedy.

The suspect, identified by federal law enforcement officials as James Holmes, 24, is in police custody. KUSA reports that Holmes kicked down an emergency door at the theater, threw in some type of a smoke bomb and began shooting when moviegoers started to run.

Witnesses say they heard a series of explosions and up to 20 gunshots after the scene grew chaotic. About 100 witnesses were taken to a local high school to be questioned by police.
