An unfinished trailer for ‘Spider-Man: Beyond the Spider-Verse’ reportedly leaked on X, prompting co-writer and producer Chris Miller to criticise the circulation of incomplete footage. The incident matters because the film is a major forthcoming release and leaks can distort audiences’ first impressions of work that has not yet been fully rendered or officially presented.

The third ‘Spider-Verse’ film is scheduled for release on 18 June 2027 and will conclude Miles Morales’s story after several delays. It follows other recent high-profile leaks, including footage connected to ‘The Odyssey’, ‘Spider-Man: Brand New Day’ and ‘Avatar Aang: The Last Airbender’; the latter led to an arrest in Singapore. Footage from ‘Beyond the Spider-Verse’ had previously been shown exclusively at CinemaCon.
