"Hughes was personally not happy with the ending of his previous film
Pretty in Pink (1986); in the script and the original cut of the film Andy (
Molly Ringwald) wound up with her best friend Duckie (
Jon Cryer). Test audiences disliked that ending, however, so a new ending was shot where Andy wound up with Blane (
Andrew McCarthy).
[2] Hughes was always unhappy with this version, which led to a falling out with
Pink's director,
Howard Deutch."That's from Wikipedia about the movie. This doesn't mention anything about Molly but I saw an interview on, I think, the original DVD where it's talked about. She specifically mentions that she couldn't ever see herself dating John Cryer. Regardless of why the decision was made, Hughes felt it was the wrong decision and I agree.
