THIS STORY CONTAINS SPOILERS FOR "morbius."
When Michael Morbius saves his friend Milo’s life, Dr. Nikols (Jared Harris) says he can send Morbius to a “school for gifted children” in New York. X-Men fans will know he’s referencing Xavier's School for Gifted Youngsters, but it’s just a reference — when the X-Men return, it’ll be in the MCU.
In a conversation between Nikols and Milo, the wealthy villain says he recently crossed paths with a dangerous “Russian gentleman,” implied to be Kraven the Hunter, a longstanding “Spider-Man” villain. Sony is working on a “Kraven” movie with Aaron Taylor-Johnson.
Morbius works towards curing his unique blood disorder at Horizon Labs, which is actually a huge location in “Spider-Man” history. Peter Parker worked there during Dan Slott’s run on the character, and of course, Morbius works for Horizon in the comics as well.
At one point, Morbius transforms into a monster and slaughters a gang of mercenaries aboard a ship called the Murnau. This is a reference to F.W. Murnau, who helmed the first-ever vampire movie, “Nosferatu” (1992), and in that film, Count Orlok also kills several people on a boat.
When FBI Agent Rodriguez (Al Madrigal) investigates the Murnau, she mentions “that thing in San Francisco,” a reference to Eddie Brock (Tom Hardy), AKA Venom. The “Venom” films take place in the same universe as “Morbius,” as the film reminds us more than once.
