Found this movie online last night... it was a hoot... and damn, Kathy Shower was sweeeeeeeeeeeet!!
That was the goofy part about the movie. Aside from Kathy Shower's obvious lack of any real acting talent, the other actors in the movie weren't that bad. David Keith alone probably saved this movie from a potential disaster (my favorite movie performance of his is still The Indian In The Cupboard (1995)
), but even the bit actors, especially the extras in the tribe, were convincing.
