With all the buzz surrounding possibilities for the next Batman villain, let's not forget about Spider-Man 4.
Sam Raimi recently told Empire Magazine that he has a character in mind to take on Peter Parker in this franchise's next installment.
"I like it in the Marvel comics when Spider-Man fights Morbius... He's really cool. A vampire! I like that combination of superhero plus supernatural," Raimi said.
A bit of background for non-comic book geeks:
Morbius was a Nobel-prize winning biochemist. He attempted to cure a rare blood disease with a combination of vampire bats and electroshock therapy... leading to vampire-like characteristics, as well as a really bad headache.
