Before production started on Spider-Man: Homecoming, we knew that Tom Holland was playing Peter Parker, Marisa Tomei was playing Aunt May, and Robert Downey Jr. was returning as Tony Stark/Iron Man from Captain America: Civil War. While several cast members signed on before filming began this summer, no further characters were confirmed until Comic-Con, when director Jon Watts announced several character names, including Tony Revolori as Flash Thompson, Zendaya as Michelle, Jacob Batalon as Ned and Laura Harrier as Liz. If a new report is to be believed, then it seems the director was trying to conceal the true identity of Zendaya's character. There will be potential SPOILERS below, so read on at your own risk.
The Wrap has learned that Zendaya is actually playing Mary-Jane Watson. Neither Sony nor Marvel would confirm the report, and it seems unlikely that we'll get any confirmation until the movie hits theaters, or possibly when the first trailer arrives at some point next year, or perhaps even early this year. There had long been speculation that her character Michelle was just a ruse, although some believed that her character is actually Michelle Gonzales, a recent addition to the comic book continuity who Peter Parker first meets as an adult.
There have also recently been rumors that new casting addition Angourie Rice, who is coming off a breakout role in The Nice Guys as Ryan Gosling's precocious daughter, is actually playing Gwen Stacy, Peter Parker's other famous girlfriend from the Marvel Comics. Both Mary Jane and Gwen have been portrayed on the big screen before, with Kirsten Dunst playing Mary Jane in Sam Raimi's Spider-Man trilogy, and Emma Stone playing Gwen Stacy in The Amazing Spider-Man and The Amazing Spider-Man 2. Regardless of the rumors, Angourie Rice's character has yet to be confirmed.
Michael Chernus recently joined Spider-Man: Homecoming as The Tinkerer. He joins a massive cast that also includes Michael Keaton as the main villain Vulture along with Michael Barbieri, Martin Starr, Isabella Amara, Jorge Lendenborg Jr., J.J. Totah, Donald Glover, Kenneth Choi, Hannibal Buress, Bokeem Wodbine, Michael Mando and Abraham Attah in unspecified roles. Rumors have surfaced that Michael Mando is playing the villain Carnage, while Abaraham Attah is rumored to play Miles Morales, but it isn't known when we'll get confirmation on these characters.
Jon Watts (Cop Car) is directing Spider-Man: Homecoming from a script by John Francis Daley and Jonathan M. Goldstein (Vacation). Kevin Feige and Amy Pascal are producing, with Marvel and Sony setting a July 7, 2017 release date. As of now, the superhero movie has that date to itself, but it will open one week before 20th Century Fox's War For the Planet of the Apes and a week after Uncharted, Despicable Me 3 and The House. We'll be sure to keep you posted with more updates as soon as they come in.
