Murphdogg,
I thought that was the movie starring Kurt Russell that was filmed in Yuma when I lived there so I googled Dune and it says it's about...
http://www.imdb.com/title/tt0087182/ - Space Travel, Blood Drinking, Religion, Homosexuality and a Giant Worm.'
look on the bright side, at least everybody knows your not religious.
JTF made me do it.
j/k...everbody knows you aint into blood drinking, homosexuality or anyything else vampire related, I really thought it was that other movie. ;p
