Spider-Man 4

Spider-Man 4 was a proposed sequel to Spider-Man 3 with a 2011 release.

Plot
The alleged plotline for Spider-Man 4 picked up five years after the events of Spider-Man 3 and had Peter Parker leaving Mary Jane and entering into a relationship with Felicia Hardy, the Black Cat. They are brought into conflict, however, when Peter kills her father, the sinister super villain known as the Vulture. The script ended with a despondant and regretful Peter discarding his Spider-Man suit, ending the series on a sour note.

Why It Was Cancelled

 * 1) Spider-Man 3 got polarizing reviews from critics and audiences.
 * 2) Many fans were disappointed with Spider-Man 3.
 * 3) Sam Raimi, the director of the first three films admitted that he was exhausted and unhappy with the third film and decided to cancel the fourth film.
 * 4) The release date became an issue since Sam Raimi couldn’t meet the Summer 2011 release date that Sony wanted.
 * 5) Sony wanted multiple villains in the film but Sam Raimi wanted to stick with only one.
 * 6) Bill Nunn pursued his career to star in other films before he died in 2016.
 * 7) The storyline championed by Raimi was dour and downbeat, with a main antagonist that wasn't seen as marketable enough by Sony executives, who preferred someone more visually interesting, like Electro or Carnage.
 * 8) Raimi wanted to push the film's release date back in order for a better script to be written after being dissatisfied with previous drafts. This angered Sony, who opted for a cheaper reboot which already had a script completed, one which was thought to be better than the scripts for Spider-Man 4.

Results

 * Spider-Man 4 was permanently cancelled.
 * Marvel hit the reset button with two reboot films The Amazing Spider-Man in 2012 and The Amazing Spider-Man 2 in 2014. Then in 2017, Sony released the most recent reboot Spider-Man Homecoming as part of the Marvel Cinematic Universe.
 * Sony is releasing an animated movie about Miles Morales titled Spider-Man: Into The Spider-Verse in December 2018, which may serve as a follow-up to the events of Spider-Man 3, since an adult Peter Parker will appear in the film as Miles' mentor. However, Toby Maguire will not reprise his role as Spider-Man in the film, as Jake Johnson is voicing the character.
