I'm not sure that you'd even want to include this as a trivia point in the wiki anywhere, but 2NE1 fans, or at least Sandara Park fans might find this interesting. Sandara's "In or Out" was remixed to promote Army of the Dead, and while she wasn't involved directly, they honored her with a zombie made up to look like her. The music video and more information about it can be found over at the Armyverse wiki here:
