WWE and Batista still have a fine relationship. They plugged his Army Of The Dead film in a very interesting way for WrestleMania Backlash.
The Miz and John Morrison ran into some zombies backstage. Yes, that really happened. Then the zombies chased them into the lumberjack match that The Miz had previously booked against Damian Priest. The zombies acted as lumberjacks.
The ThunderDome was transformed into a zombie ravished wasteland on the giant video screens. Then The Miz and Damian Priest had their match as planned, only with zombies.
This was not expected at all, and only adds to the fact that you never know what can happen in WWE. This was also likely a substantial payday off a promotional partnership.
In the end, Damian Priest got the win and then he celebrated… with zombies.
