Chris Martin
That's not just any zombie, that's Coldplay frontman, Chris Martin. In Shaun of the Dead, the "Yellow" singer plays a fan supporter at the ZombAid fundraiser. Even weirder, he plays himself again at the Coldplay show. He even appears on the soundtrack playing a cover of the Buzzcocks song "Everybody's Happy Nowadays" with Irish band Ash. Maybe this flick should be called the Chris Martin of the Dead.
