When the script was written in the 1970s, which film was planned to star Steve McQueen and Diana Ross?

The switch was never explained or maybe I missed it.

Player #47280495, Perhaps the the 12 years that McQueen had been dead before the film came out is a pointer

The chemistry between Costner and Whitney Houston was palpable. this is one of my favorite movies. the song is amazing.

Player Bengal Mama, read the the explanation it says 1980.

Player #53553731, Probably because it is an obscure movie fact that not many know of.

TRUE CANADIAN Laurel, When did McQueen die? I know he was very young and tried every cancer remedy known. Sad, sad to lose him so young.
