Dexter & Zombies. What's the point of serial killin' 'em if they just come back to feed on the living?
Mad Men & Zombies. Who'd sell them and at what price? Also what would the zombies think of sexist and discriminatory office politics - would they demand better wages? Maybe just a chance to prove themselves - they've got brains and they can show you, and also borrow yours.
Inglourious Baserds & Zombies. Heck, add some mystical Thule society stuff interested in the spear of Longinus and the mash-up of pulp cliches would be complete. But would it be watchable?
