I`ve looked at IMDB, and she played Zula in Conan the Destroyer (1984). But I have not seen her in any movies. To me she is famous for her music and modelling.
I use to play in a band myself obviously and I always dismissed women on vocals for the good hard rock stuff. But Nina has 1 badazz voice, I wish I could have jammed with her back in the day ...... One Cool Chick ..lol
