A video published by Sony Channel Latin America teases the arrival of Tobey Maguire and Andrew Garfield in Spider-Man 3.
Since Strange is set to explore the multiverse in his next solo movie, it is highly likely that his job in Spider-Man 3 will be to prepare Holland's Spidey for some inter-universal adventures which will bring him into contact with previous live-action Spider-Men.
What better way to welcome Holland's Spider-Man into his new, separate series than by teaming him up with Garfield and Maguire?
