Spider-Verse writer Chris Miller is not happy about those footage leaks

Specifically, Chris Miller—one half of Lord and Miller, one of the most productive and influential of Hollywood’s various dynamic duos in recent years—hopped on Twitter this week to express unhappiness about a recent leak of material purportedly from the forthcoming Beyond The Spider-Verse. (Which, after various delays, is now being aimed at a June 2027 release date.) Miller’s ire wasn’t excessive or anything—he simply wrote that he was “Not a fan of leaks of unfinished, not fully rendered footage”—but it was an acknowledgement that this stuff is getting passed around this weekend, alongside promo materials for this December’s Avengers: Doomsday.

And it’s not like these leaks were coming from high-end espionage (or even what we’ve now come to think of as “the Netflix method,” i.e., just walking into a streamer’s office building and making off with a hard drive.) Both videos were reportedly from footage that the studios showed off of the movies themselves, but didn’t put online. In the case of Spider-Verse (per Gizmodo), that meant a video reportedly shown at Cinema Con back in April, showing the first few minutes of Beyond. (The Doomsday footage, meanwhile, apparently came from Marvel’s big Hall H show at Comic-Con this year.) In that sense, Miller’s comments actually came as a relief to some fans: Several viewers had noted that the footage—in which Miles Morales has a very uncomfortable family reunion of sorts—looked in some ways unfinished, so getting confirmation that it wasn’t the final version of the movie allayed fears. (Although not worries that Beyond is suffering from the same animator churn that reportedly plagued Across.)

All of which, honestly, feels like a consequence of recent pushes to try to keep these videos from going online in the first place. We understand not wanting to have your rough drafts floating around in gen pop—and wanting to have something special to show off for fans actually willing to make the trek out to a convention in person—but it also speaks to the basic impossibility of keeping anything secret in a world where every single person in your audience has a high-definition video camera lurking in their pockets.
