First introduced in the Amazing Spider-Man comics, Dr. Michael Morbius is a scientist who attempts to cure his rare blood disease, but ends up turning himself into a blood-thirsty vampiric creature.
Even though Morbius fights Spider-Man in the comics, unfortunately, we won't see Leto face off against spunky Tom Holland in any of the Marvel movies. Much like Sony's upcoming Venom spinoff starring Tom Hardy, Morbius is not under the MCU umbrella. This also means that, like Venom, we can expect Leto's flick to favor a darker vibe, allowing him to fully flex his villainous muscles.
Variety reports that Morbius has no release date yet, but is expected to start production this year.
