Given that Spider-Man: Homecoming has been shooting for several weeks now, we're going to go ahead and assume that Orange Is The New Black's Michael Chernus hasn't just leapt on board the film, but is already shooting and word has only arrived now. Regardless, he's playing Phineas Mason, AKA The Tinkerer.
Since Homecoming, which features the first stand-alone adventure for Tom Holland's take on Peter Parker and his web-spinning alter ego, already boasts the services of Michael Keaton as the Vulture (even if that still hasn't been officially confirmed despite concept art of the character) and Logan Marshall-Green as an unnamed threat, we'd figure the Tinkerer – torn from the pages of Marvel comics, and a genius with the ability to create amazing gadgets out of household appliances – will be a more minor character. Perhaps he'll be the one to supply Vulture with his wings? He's still a good character to have in the film, especially given Peter's love of tech and the presence of Robert Downey Jr.'s Tony Stark, who helps the lad with some equipment upgrades of his own.
Cop Car's Jon Watts is directing the movie, with Marisa Tomei, Donald Glover and Tony Revolori among its crammed cast. Spider-Man: Homecoming should be out here on July 7 next year.
