'I hope we have done right by you' - Jolie The preview audience for A Mighty Heart, chronicling the murder of Wall Street Journal reporter Daniel Pearl by Islamic extremists, got an unexpected bonus when the film's stars, Angelina Jolie and Dan Futterman, dropped in unannounced. Jolie, who stars as Pearl's widow Mariane, told the Wednesday evening audience at the Museum of Tolerance in Los Angeles, that throughout the filming she was always aware of the Pearl family's "unimaginable suffering." "I hope we have done right by you," she told the reporter's parents. The Paramount Vantage film, which opens June 22 in the United States, was directed by Michael Winterbottom and co-produced by Brad Pitt. The preview raised $15,000 for the Daniel Pearl Foundation, established by Dr. Judea and Ruth Pearl to promote understanding between different cultures and religions. Speaking of his five-year old grandson Adam, born a few months after his father's slaying, Judea Pearl urged him to keep his faith in humanity, despite all obstacles. Ruth Pearl said she hoped that her son would be remembered for the way he lived and worked, rather than by the way he died. A Mighty Heart is based on the book of the same title by Mariane Pearl and Sarah Crichton. Daniel Pearl was decapitated in Karachi in January 2002, but although four men were convicted of the crime and are appealing their sentences, new alleged accomplices continue to turn up. Only last week, Pakistani police arrested two men who, they say, are linked to Pearl's kidnapping and death. In March, the Pentagon released a transcript of the interrogation of Khalid Sheikh Mohammed, the alleged al-Qaeda mastermind behind the 9/11 attack, and now held by the U.S. military at Guantanamo Bay. According to the interrogation transcript, Mohammed boasted that he had personally beheaded Pearl, stating that "I decapitated with my blessed right hand the head of the American Jew, Daniel Pearl."
