As part of a Q&A session, director Zack Snyder revealed the details of the Army of the Dead enemies that a group of mercenaries who have gone to Las Vegas for money will have to face. The group will meet two types of zombies: normal and alpha.
We have two categories of zombies in the movie: alphas and regular zombies. The Draggers are regular slow zombies, and there are alphas. They are an evolved version of zombies and there are a lot of them … They are fast, and we treat them almost like intelligent wolves. They fight in packs and they have a pack mentality.
Snyder also said that the film will try to tell as much as possible about how and why the infection began in order to set the foundation for the cinematic universe. It will include a prequel, which has already been filmed, and an animated show.
Army of the Dead hits Netflix on May 21st.
