One of the most interesting Marvel comics of all time was Strikeforce Morituri, which took place outside of the main Marvel continuity and had a simply incredible premise: when aliens invade the Earth humans fight back by inventing a system to give people super powers. The drawback: you die a year after getting the powers, which is called the Morituri effect.
Strikeforce Morituri was a comic predicated on the concept that all your favorite characters would die, which is more than a little great. Of course it didn’t last (despite being MASSIVELY advertised in Marvel comics, as any 1980s Marvel reader can tell you).
Now the comic is being developed as a movie with original creator Peter Gillis adapting his original work along with Connor Cochran. But before you get TOO excited, this isn’t Marvel Studios - it’s being developed at Waterman Entertainment, which is run by the guy who produced films like Alvin and the Chipmunks, Casper and Kull the Conqueror. A bad, bad track record. But since Morituri is SO different from all that stuff, maybe they’re branching out.
Don’t expect all the characters to die in the movie - by the time the comic ended they found a cure for the Morituri Effect, which really removed the whole point of the concept. But which makes a happy, franchisable end for the film!
