She has never recovered since “Desperately Seeking Susan” in 1984. She thought she was going to be the break-out star, and Madonna completely stole the show. I know, we don’t give a crap about these fools, but I was looking back in time with my 1980’s glasses.
I think it was the other way around- Madonna was supposed to be the star and Rosanna Arquette stole the show.
But man was she hot back then!
Check her out in “The Wrong Man” movie.
Too bad about her brain though...
