Marvel Studios maintains legendary secrecy around its productions through multiple protective measures including code names for projects, isolated set filming, and restricted script access that prevents actors from reading complete screenplays.

This confidentiality strategy protects plot twists from leaks while allowing creative flexibility during production, though it sometimes leaves cast members uncertain about their characters' full narrative arcs or the film's complete story structure.

One actor reveals this method really affected his comprehension of the movie entirely.

Alan Cumming spoke candidly during a SiriusXM interview about his Avengers: Doomsday experience, admitting.

"I don't fully understand the plot," despite returning as Nightcrawler alongside familiar X-Men faces.

His confusion makes sense considering how fragmented his filming experience became. Cumming revealed that much of his work happened against blue screens, giving him little visual context for the enormous Marvel crossover unfolding around Kurt Wagner.

He recalled one rare backlot shoot where a crew member began explaining a scene involving giant robots. Cumming quickly decided the exposition was unnecessary. He simply wanted to know where to point and what action to perform, joking that he knew he was there to run around.

Joe Russo recently confirmed that the screenplay itself evolved during production, describing it as a "living organism." Florence Pugh became part of an even stranger example. Cumming said he met Pugh at the Emmys and joked that she had apparently lain on top of him during filming, although they had never actually worked together. Pugh revealed that she performed with Cumming's body double, while he filmed with hers.

With Marvel keeping even its own stars guessing, another famously secretive Spider-Man question refuses to disappear.

Andrew Garfield remains one of the biggest casting mysteries surrounding Avengers: Doomsday. Marvel has never officially announced him for the movie, while Garfield has issued an emphatic denial. Asked during a GQ interview whether his Spider-Man would appear, the actor responded with an unequivocal no.

But Marvel fans have a very good reason to remain skeptical. During the buildup to Spider-Man: No Way Home, Garfield repeatedly denied that he was returning as Peter Parker. The finished movie ultimately revealed him alongside Tom Holland and Tobey Maguire, turning months of denials into part of MCU history. Variety even acknowledged that fans may struggle to trust his latest answer because of that previous campaign.

That does not mean Garfield is secretly appearing in Doomsday. His involvement remains completely unconfirmed. Still, his denial cannot shut down speculation in the way another actor's might. Garfield has also previously expressed interest in playing Spider-Man again when the project offers a creatively worthwhile idea.
