The Amazing Spider-Man film series ended prematurely, but one idea for a further installment would have had Emma Stone return to the franchise not only as Gwen Stacy but also as Carnage. The Amazing Spider-Man 2 was a commercial success, and while it’s viewed in a positive light by die-hard Spider-Man fans, the film’s overall reception was mixed, leading Sony to consider numerous ideas (some more dubious than others) before rebooting the character yet again and allowing him to join the MCU. One such idea would have seen Spider-Man's Gwen Stacy return in Carnage form. While this seems like one of Sony’s stranger ideas, it is based on the comics and could have made for an entertaining story, if handled well.
The Amazing Spider-Man films follow the Marvel Comics source material at a comparable level to the Sam Raimi Spider-Man Trilogy, though Marc Webb’s duology was inspired by different eras of the Spider-Man comics. While Raimi’s films were inspired by the Stan Lee and Steve Ditko era (among others), the Amazing Spider-Man films were more influenced by Brian Michael Bendis’ Ultimate Spider-Man comics and the mainstream comics of the 1970s, by Gerry Conway and John Romita Sr. For instance, The Amazing Spider-Man 2 loosely adapted the tragic Death of Gwen Stacy story from the Conway era while introducing iterations of Electro and the Rhino that resemble their Ultimate incarnations.
