Vulture and Scorpion will be played by Billy Zane and Jason Biggs, respectively. The report notes that both villains use mechanized suits, fueling speculation of a Tony Stark cameo.

Rachel Fox will play Mary Jane Watson, with Sami Gayle as her best friend Liz Allan, and Miranda Cosgrove as Betty Brant. Timothée Chalamet is Harry Osborn, and Tyler Posey as Ned Leeds. Jacob Latimore as Flash Thompson.

Hugh Laurie is listed as J. Jonah Jameson; Forest Whitaker as Robbie Robertson.

I would take all this with a HUGE grain of salt as the script hasn't even been written yet.
