If you don't already know, Morbius was a scientist who tried to cure himself of some more or less unspecified blood disease.
The Hollywood Reporter broke the story about the Morbius movie, but it offered no details about the script's take on the title character. Tom Holland debuted as the latest wall-crawling superhero in Captain America: Civil War, and found success in his own film this summer with Jon Watts' Spider-Man: Homecoming. While the actual character of Peter Parker is now being lent to Marvel Studios, hence why Spider-Man: Homecoming took place in the MCU, Sony still has the rights to all the other Spider-Man characters.
The movie, simply titled Morbius, was written by Burk Sharpless and Matt Sazama, who most recently wrote the live-action Power Rangers movie for Saban and Lionsgate.
Whether Spider-Man is legally capable to show up in these films is a bit murky, as Sony and Marvel seem to change their statements every other week regarding the matter.
Morbius, who first appeared in The Amazing Spider-Man #101, dated October 1971, was an intriguing character for the twilight era of comics' Silver Age, arriving just after the Comics Code Authority lifted its ban on vampires and supernatural characters. The issue is significant because it's the first issue not penned by Marvel Comics legend Stan Lee.
He's well-known to fans of "Spider-Man: The Animated Series", which ran on Fox Kids from 1994 to 1998, and featured a Morbius plotline.
As such, Morbius is considered somewhat of a tragic figure, with a healthy does of anti-hero to Spider-Man. Eventually, he's turned into an anti-hero of his own right, similar to Venom. It'll start with next year's Venom, slated to star Tom Hardy, and continue with Silver & Black, focused on the Spider-Man characters Silver Sable and Black Cat.
Again, it's not clear at this point if (or how) a Morbius movie would tie into the Marvel Cinematic Universe, or if he'd be a part of the still-developing Sony universe of standalone Spider-Man-related films.
