Weirdly Karen Lynn Gorney...kinda
She played Stephanie, the love interest, in Saturday Night Fever; while that was definitely considered Travolta's show you think she'd stay and build off what attention she got from being in that movie.
But instead she quit acting after making that movie, started an art gallery, and then came back to the business 14 years later and has been doing bit roles here and there. For instance did you know she was in Men in Black? Supposedly she was!
I wonder what made her decide to quit acting after being in such a huge movie like that? And why she decided to go back?
