Spider-Man: No way Home - Tobey Maguire and Andrew Garfield part of the movie?

Since it was first reported back in December 2020, their supposed return has been speculated so much that it essentially became a fact – despite there actually being no confirmation from Sony, Marvel Studios, or the actors involved.
In fact, everybody involved was insistent that Maguire and Garfield wouldn't be back as Peter Parker in the new movie. Garfield called a leaked set photo a fake, while Holland said in February 2021 that "they will not be appearing in this film".
Some reviews had already spoiled it, but yes, Tobey Maguire and Andrew Garfield do reprise their roles as Peter Parker/Spider-Man in No Way Home – and it's every bit as glorious as you'd have hoped.
Doctor Strange's spell to make everybody forget Peter is Spider-Man goes wrong when Peter can't stop messing with it. Instead of making everybody forget, it starts to pull in everybody who knows Peter is Spider-Man from any universe.
One rumor that didn't turn out to be true is that Kirsten Dunst and Emma Stone would be back as Mary Jane Watson and Gwen Stacy, respectively. They're spoken about by their respective Peters, but neither of them makes an appearance.
While that might be a disappointment to Spider-Man fans, the trio offers up plenty of fan service moments to make up for it. Will they be back in Spider-Man 4? Probably not as they return to their own universes, but you never know...
