Looks like this one is back on, with Steven S. DeKnight directing (first time directing a movie, but he has been the showrunner for Daredevil). Del Toro is now producing. My big question though, is... will Ron Perlman be returning?
Or will he (Del Toro) ever get At The Mountains Of Madness made?
Yes and no.
Yes Ron Perlman will be back, or so it is rumored, in what is now known as "Pacific Rim : Maelstrom."
And no. "At the Mountains of Madness" is in what is known as "developmental hell," but . . .?! at this time, it does look like the film will never be made.
