At 11:32, "Dances with Wolves" director and actor tells about the time he got a call, out of the blue, from Steven Hawking who wanted to come and meet with him. After a bit a visiting, Kevin said, "So, what's up, man, what do you wanna know?" To which, Steven Hawking replied that he wanted to know everything about Whitney Huston, who Kevin Costner had acted with in the movie "My Bodyguard."
There's been speculation that Whitney Huston was murdered, and there's also been speculation that Steven Hawking was compromised, having been to "the island." Wondering if someone was pressing Hawking to go see if Whitney was talking to people like Costner about problems she might have been having with certain people in her life. Sounds like Costner knew nothing and just relayed stories about having worked with her, and her being a wonderful woman to him.
