Is it true that Sharon Stone has started her career from B grade movies?

Sharon Stone - IMDb (http://www.imdb.com/name/nm0000232/?ref_=sr_1)

You can look at the ones she did and consider if they were B movies are not, A few of them would have to improve to be a B movie in my book

That is what she is well known for. I really don't know any of her B movies. Seems she is still doing B movies such as Border Run (2012). My cousin went out for her a couple times when she was Miss Crawford County.
