Bryan Singer has revealed, via his Instagram account of all places, that he will follow-up X-MEN: APOCALYPSE with an adaptation of 20,000 LEAGUES UNDER THE SEA. 

Here is the Instagram post:

There is no word if this is a page one rewrite or if he is continuing from the work that David Fincher had done on the project. I’m certainly curious about this one. Bryan Singer is a filmmaker whose career has hit epic highs and some pretty devastating lows. I can’t think of a studio blockbuster as mishandled as JACK THE GIANT SLAYER, but he also deserves a ton of credit for pretty much every superhero film that has taken itself seriously since 2000… For better or worse.

UPDATE: This project is actually being set up at Fox and therefore has no connection, besides the source material, to the project David Fincher was setting up at Disney. I wonder if this changes things for that production.
