People reports the charismatic Princess was interested in the project, with Costner explaining it was Sarah Ferguson, ex-wife of Prince Andrew, who connected the Hollywood star with the royal. "Sarah was really important," he noted, adding, "I always respect Sarah because she's the one that set up the conversation between me and Diana." The star also revealed, "She was the one that set it up, and she never said, 'Well, what about me? I'm a princess too.' She was just so supportive of the idea."
Costner explained that although the most famous woman in the world at the time was interested in the project, she was nervous about one particular aspect of appearing in the film. "I just remember her being incredibly sweet on the phone, and she asked the question, she goes, 'Are we going to have like a kissing scene?' She said it in a very respectful way." The actor added, "She was nervous because her life was very governed. And I said, 'Yeah, there's going to be a little bit of that, but we can make that okay too.'"
Sadly, the film never got off the ground as Princess Diana passed away, at the very young age of 36 (via Biography).
