Army of Darkness is one of the greatest movies of all time.  Of course, I am more of a fan of Evil Dead II (the movie that answers the ultimate question, "How much crap can happen to one guy in forty eight hours?") but this move absolutely rules.  Bruce Campbell is the man.  He has written two great books, "If Chins Could Kill: Confessions of a B Movie Actor" and "Make Love! the Bruce Campbell Way".  You can find and order both books here.
