The release window has decreased so much that it is merely a matter of months for people to see the movies they missed in theaters. Which used to be a minimum of six months has been shrunk down to a mere three months. A little less for digital copies. With all that being said, Spider-Man: Homecoming will be available in stores before Halloween.
Sony announced that the digital version of the film will be available starting September 26th, while the physical copy of the film will be available on October 17th. The 4K Ultra HD release will include the film with Dolby Vision HDR and Dolby Atmos audio.
4K extras will include The Spidey Study Guide and a Photo Gallery. Blu-ray extras will include those, plus 10 Deleted Scenes, a Gag Reel, 7 featurettes (A Tangled Web, Searching for Spider-Man, Spidey Stunts, Aftermath, The Vulture Takes Flight, Jon Watts: Head of the Class, and Pros and Cons of Spider-Man), plus the Rappin’ with Cap: Captain America PSAs.
With the shortening amount of time between the releases in theaters versus home release, this will make available all the Marvel films available for purchase before the next movie is released. This will allow us all to have those Marvel movie marathons at home before the next movie. That would be a bit more relaxing.
