An Arab-American civil rights organization has asked "American Sniper" director Clint Eastwood and actor Bradley Cooper to denounce hateful language directed at U.S. Arabs and Muslims after the release of the film about a Navy marksman.

The American-Arab Anti-Discrimination Committee (ADC) said in a letter to Eastwood and Cooper that its members had become targets of "violent threats" even before "American Sniper" went into general release. The letter said Eastwood and Cooper, the film's producer and star, could bolster the ADC's message of tolerance.

"It is our opinion that you could play a significant role in assisting us in alleviating the danger we are facing," said the letter, dated Jan. 21.
