Kevin Costner says that the late Princess Diana was "genuinely excited" about co-starring with him in a sequel to his hit film The Bodyguard. "I had talked with Princess Di a couple of times," the actor told British talk show host Michael Parkinson in an interview to be aired Saturday. "I explained to her that I was going to try to make this movie for her, and she was genuinely interested." Costner — who reportedly received the final draft of the script the same day Diana was killed in an August 1997 Paris car crash — admits he was "devastated by it. She was a very graceful woman and it is a great loss to all of us." The original 1992 film co-starred Whitney Houston and grossed $121 million.
