In an interview with People magazine, Kevin Costner (the star, and the bodyguard, of The Bodyguardwith Whitney Houston) revealed that Princess Diana was considered for a starring role in a sequel to the film.
In fact, he said he had a conversation with her about it before her death.
Apparently the studio liked the idea of doing a sequel: and so did Princess Diana. When Costner asked if it was something she would like to do, she said yes. He also said she was a little nervous about the idea of doing a "kissing scene," but he assured her that they would make it OK. He also said she was incredibly sweet on the phone.
