Although Zack Snyder has plenty of projects in development, one oft-mentioned dream film is a disaster waiting to happen. Snyder currently has a first-look deal with Netflix, which has produced the zombie movie Army of the Dead and upcoming sequel Planet of the Dead, with the sci-fi movie Rebel Moon set to release in 2023. Other Snyder projects that have been announced include Horse Latitudes, a drama about a war photographer in South America, and a version of the King Arthur story set during the American gold rush. However, it is Snyder's long-discussed adaptation of Ayn Rand's 1943 novel The Fountainhead that poses the biggest potential danger.
