I second the motion for Bubba Ho-tep.. Bruce Campbell is the best Elvis ever..(and the explination of how Elvis is "alive" was very clever)
Shaun of the dead, kind of more of a comedy, but the zombies arent treated with comedic intent, and thats why it works, plus its just a great movie.
Any of George A. Romero's "living dead" trilogy (i know there are four, but true fans know there are three, note how in Night of they are referred to as Ghouls, or those things, not zombies..and while considered some as "B" films this is the first trilogy of films to ever be remade, showing an influence beyond any other film in any genere)
John Carpenters Halloween...(hopefully Micheal Myeres' next victim is Rob Zombie)
I havent seen it , but isnt there a movie called Shaolin Vs. Evild Dead ?
Dracula .
Creature from the black lagoon
Christine
Sleepy Hollow
From Hell
The Shining
Creepshow& Creepshow 2
War of the Worlds
