The cast for Marvel and Sony's Spider-Man: Homecoming just keeps getting bigger and bigger, with Michael Keaton recently joining, rumored to be playing the villainous Vulture. It still hasn't been confirmed when exactly production will begin, but today we have word that another youngster has joined the cast. 14-year-old Michael Barbieri, who was recently cast as Timmy in Sony's The Dark Tower, has entered negotiations to come aboard.

If he does sign on, he'll join Tom Holland as Peter Parker/Spider-Man, Marisa Tomei as Aunt May, Zendaya Coleman as the female lead, with Tony Revolori as Parker's school yard nemesis and Laura Harrier in an unspecified role. It isn't known if Michael Barbieri's character will have roots in the Marvel Comics, or if he's playing a new character created specifically for this movie. Robert Downey Jr. is also reprising his role as Tony Stark in Spider-Man: Homecoming, following Spidey fighting alongside Iron Man in the epic superhero adventure Captain America: Civil War.

Producer Kevin Feige previously teased that other Marvel Cinematic Universe characters will be featured in the Spider-Man reboot, but, other than Iron Man, we don't know what other characters may show up. It has been confirmed several times in the past that this movie will skip over the familiar origin story, with Peter Parker already established as Spider-Man in Captain America: Civil War. The story will reportedly follow Peter as he tries to balance his school work with fighting crime in New York City.

Jon Watts (Cop Car) is directing Spider-Man: Homecoming from a script by John Francis Daley and Jonathan M. Goldstein (Vacation). Marvel Studios president Kevin Feige is producing with Amy Pascal, with both Marvel and Sony setting a July 7, 2017 release date. As of now, it's the only movie set for release on that date, but it will be sandwiched between a few high-profile projects. Opening one week earlier on June 30, 2017 is Sony's Uncharted and Universal's Despicable Me 3, with 20th Century Fox's War for the Planet of the Apes arriving on July 14, 2017.

Michael Barbieri made his feature film debut in this year's Sundance sensation Little Men, alongside Greg Kinnear and Jennifer Ehle. Earlier this year, he was cast as Timmy in Sony's highly-anticipated The Dark Tower, which is currently in production and set for release on January 13, 2017. He is also attached to star in Life Now, Life Then, which is currently in pre-production.
