Though it would not say exactly how much it planned to donate, Warner Bros. is expected to contribute a "substantial" sum, according to sources.

The Hollywood Reporter says the studio will contribute to a Giving First fund that will distribute the money among several charities providing support for victims of the Aurora theater shooting and their families.

12 were killed and 59 were injured after a gunman opened fire on audience members at a midnight screening of The Dark Knight Rises in Aurora, Colorado.

Warner Bros. initially declined to release dollar figures for TDKR's opening weekend out of respect for the victims, but it was eventually revealed that the film had grossed a record-setting $160.9 million.
