3) Crisis On Infinite Earths (Every DC Movie Crossover)
The Crossover: If a TV/movie crossover is out of the question, how about a big movie event that unites various previous DC movie franchises. Much like our Spider-Verse idea, this version of the Crisis on Infinite Earths movie could see the DCEU clash with the world of Christian Bale’s Batman or Brandon Routh’s Superman. Or, going further back, Michael Keaton’s Batman. Or, given the Zack Snyder connection, the world of Watchmen? The possibilities are practically endless.
Again, like Spider-Verse, this could provide closure for those franchises that were left hanging. For instance, what happened to Keaton’s Batman after Batman Returns? Did Christian Bale’s Bruce really live happily ever after with Selina in Paris? We want to know these things, damn it!
Likelihood – 4/10: Despite this potentially being the bigger logistical nightmare ever – for this to work, all of these old stars would have to be willing to return – we can still see this happening more than the TV crossover. That being said, while the studio could probably get away with harking back to previous movies in something irreverent like The LEGO Batman Movie, in a serious, live-action outing, they may have a tougher time.
