I don't think the lead actors had much pull on these films, as they were unknown at the time.

Clearly the music, and the way it was presented were a huge factor in the success of these films.
In the case of "Flashdance"(1983) it was a success almost in spite of the studio/distributor Paramount. I watched it over the weekend and the special features. It was filled with 'unknowns'. Adrian Lyne indicated he refused the script several times, until eventually one was written that he could sign up for. There was also mention that Paramount was pretty ambivalent about the production as well.
The film caught a wave and the rest is history.
