Zack Snyder released his 2004 zombie film "Dawn of the Dead," which blew audiences away with his portrayal of the undead dystopian world, and then, instead of releasing a sequel, he stepped away from flesh-eating corpses for a long time. That's not to say the famed director wasn't extremely busy creating more cinematic gold with movies like 2006's "300," 2009's "Watchmen," and 2017's "Justice League" — as well as his eponymous director's cut from 2021 (via IMDb). Truth be told, Snyder is always up to something.
In 2021 Snyder released "Army of the Dead." A zombie-heist movie that took Snyder back to his zombie days with all the glitz and glam of a horrifying Las Vegas bloodbath. Of course, the movie itself is often compared to "Dawn of the Dead," but in an interview with ScreenRant, Snyder assured curious fans that it isn't a sequel. "I developed it right after 'Dawn' but not as a sequel. I wanted to do this other evolution in it of the zombies. So I needed another trope."
With almost two decades having passed since his revisiting of "Dawn of the Dead," and so many additions to the new "Army of the Dead" zombie-verse including, including "Army of Thieves" and the not-yet-released "Planet of the Dead" (via Variety), it seems unlikely that a sequel to the 2004 hit movie will come anytime soon. However, there will still be plenty of Snyder's zombie films to go around.
