Last week, we reported that Oscar-nominated actor Michael Keaton was in early talks with Sony and Marvel to play the main villain in the highly-anticipated Spider-Man: Homecoming. No details about the character had been given, and the deal wasn't finalized at the time of the report. Today we have a new report that talks between the actor and the studios have fallen through, and that Michael Keaton has parted ways with Spider-Man: Homecoming.

Deadline's report doesn't specify exactly why Michael Keaton dropped out of the project, but if he had stayed on, he would have joined a select group of actors to play characters from both Marvel and DC Comics. The actor portrayed the original big screen version of The Dark Knight in 1989's Batman and the 1992 follow-up Batman Returns, and while the villainous character he was set to play hasn't been confirmed, there have been rumors that the villain is Vulture. Stars such as Ben Affleck (Batman/Daredevil), Ryan Reynolds (Green Lantern/Deadpool) and Chris Evans (Captain America/The Losers) are among actors who have played both Marvel and DC characters.

The news of Michael Keaton dropping out of Spider-Man: Homecoming was coupled with Robert Downey Jr. coming aboard to reprise his role as Iron Man in this superhero reboot. Tom Holland's Peter Parker makes his MCU debut next month in Captain America: Civil War, and a scene from that movie debuted at CinemaCon last week, that showed Peter Parker being greeted in his living room by Tony Stark and Aunt May (Marisa Tomei). Fans got their first look at the new Spider-Man in last month's new Captain America: Civil War trailer, where he stole Captain America's shield.

The Spider-Man: Homecoming cast also includes Zendaya Coleman, who signed on recently to play a character named Michelle, along with Laura Harrier as an unspecified high school student, and Tony Revolori, who plays Peter's schoolyard enemy named Manuel. Jon Watts (Cop Car) is directing Spider-Man: Homecoming from a script by John Francis Daley and Jonathan M. Goldstein (Vacation). No story details have surfaced yet, but it has been rumored that Spider-Man: Homecoming will start a new trilogy, centering on Peter Parker's high school years as he juggles his crime-fighting activities with his schooling.

Michael Keaton most recently starred in the Best Picture winner Spotlight, and he will next be seen in The Founder, where he plays McDonald's founder Ray Kroc, which just released its first trailer today. He is also set to star in American Assassin, and is set to reprise his title role in Beetlejuice 2, although it isn't known when that project will go into production. Stay tuned for more casting updates on Spider-Man: Homecoming, which is scheduled for release on July 7, 2017.
