Warner Bros. is donating an undisclosed sum to the victims of last Friday's mass shooting at a screening of "The Dark Knight Rises" in Aurora, Colo., and is encouraging its employees to do the same.

A spokeswoman for Warner Bros. told TheWrap that the company communicated with Colorado governor John Hickenlooper over the weekend and made the donation to the victims and their families through Givingfirst.org [4], an organization that was identified by Hickenlooper.

"We’ve had an outpouring from employees who’ve asked how they can help and contribute, so we sent a note," the spokeswoman told TheWrap.
